Whilst I appreciate due to Corona virus that businesses are having difficulties not previously encountered. However we are now in August and whilst other supermarket chains seem to have overcome stock shortages a several months ago, ASDA (Lancing store) still seems to struggle with stock issues for online deliveries. We have been in strict self isolation since the beginning of March 2020. Taking all measures to try and avoid Convid19, we started using supermarket online grocery delivery services. Initially we were only able to obtain slots from Tesco and ASDA. At first both chains suffered stock issues with bread, rice, pasta ect, due to some people bulk buying. We opted for ASDA deliveries when possible, as initially we preferred the service and the extra care (safety wise) taken by the ASDA drivers when delivering. As time went on, we became more and more frustrated, as to obtain a slot with ASDA you have to book two weeks in advance and then not having the items we wanted on the delivery date. Our second and third shop with ASDA, having secured a slot and placing your grocery order two weeks prior to delivery. Initially we did not log back in to check the order and only received a fraction of the items we wanted, this included eggs, bread, meat and other basic essentials. There were several substitutions, for example frozen butternut squash instead of fresh carrots and peas instead of broccoli and they did refund the butternut squash, when emailed that these were no acceptable substitutions. From that point onward, we logged in one or two days before the delivery date and each time we would receive a message saying these items are not available. In some instances 50% of our shop. Many of the items we wanted are still not available, such as; Pitta bread (white or wholemeal) bake at home baguettes, some rice and pasta. Other items you would expect a super market not to run short of ASDA (Lancing store) frequently come up as not available when trying to order. For example steak and mince, pork, lamb, broccoli, carrots, a range of pies, burgers, soya milk, pasta, own brand curry sauce, strawberries, Ribenea, lemon squash, orange squash, freshly squeezed orange, Walkers chicken-salt and vinegar and cheese and onion crisps, Smith;s salt and shake crisps, Frozen peas (except then as a substitute for broccoli), lemons, cabbage, kale, rice, many types of cereal, fresh burgers and frozen burgers, various breads, The list goes on. Although we have always been able to get plenty of bananas and avocados , one can only surmise that the stock controller for ASDA Lancing like bananas and avocados, not presumably together. Mid July we moved house (tricky whilst still self isolating) I placed an order to have groceries delivered in a few days after the move. Being concerned that I could not add to delivery addressed in my ASDA account I called ASDA customer services and was told that because my debit card was still registered at the then current address, I could not have the groceries delivered to another address. explaining that having to order the shop two weeks in advance and still having to purchase things for the move, I was not changing my details with the bank until the last minute. I was told that if I secured a slot and placed an order I would be able to switch the address once the billing address for my debit card was updated. I actually did this four days after the conversation with customer services, after the payment to the moving company had been processed. Once conformation the address had been changed arrived from my bank, I logged on to ASDA and tried to change the delivery address, I tired everything I could think of. I called customer services and was told as after 7:00pm on a Friday, I would need to call back Monday when the relevant team would be there. I called and was told it was not possible to change the address, that I would have to book another slot. Which would mean having a week without groceries and we had run most things down not to have to move loads of food. I explained this and received apathy and total nonchalance, even after offering to provide the letter written by my GP advising as a person at extreme risk I needed to strictly isolate. I was told that is no other option, even though the advise I received from ASDA had led to the issue. Now facing a week without groceries, I tried Sainsburys and we have not suffered any of these issues with them. Although admittedly they are more expensive.
