Loyal Sainsbury's customers, kept getting offered money off vouchers to use online. As not great online shoppers ordered a bulk of dog food (as we have many) with £18 off £60 spend. Ordered 'click & collect' and was given a collection date of this morning between 8-9am. Drove the 20-30 mins to the store to collect, was kept waiting 15mins then advised they did not have the stock, our order has been cancelled, and we should have used the online 'bulk order' system, whatever this is. No notification of this at the point of order, no notification our order had been cancelled and why give me a collection date of today? Rang their so called 'customer service' who did nothing but advise it was in their terms & conditions online......Really I was supposed to read all their terms & conditions to order dog food. Sainsbury's what a let down, great stores, pricing and product range but stick to what you do best and don't make loyal customers like us feel so annoyed with you! Let Amazon do the online and concentrate on keeping your core business loyal.
