Due to lockdown and the fact that I am classed as vulnerable I have been relying on Sainsburys home delivery for the past few weeks - for the previous 25 years I have visited their local store. Yesterday, I was advised by text one hour before my home delivery was due that it was cancelled - no reason was given. It also transpires that Sainsburys has blocked access to my online groceries account. I contacted Sainsburys three times to determine the reason and have been given various explanations as follows; 1) We can't tell you 2) It might be a fraud 3) It might be something to do with your address 4) We will call you back with an explanation (which they didn't) 5) There seems to be a problem with credit card authorisations with one of the banks In my opinion 5) seems the most likely explanation and it must be affecting many other customers. Has Sainsburys warned their customers of the problem or simply left those vulnerable customers bereft of assistance or a plausible explanation for rejecting their business? There is no evidence that any action has been taken in this regard - bizarrely, I was told that the team investigating the issue don't work at weekends so it could be next week before anything is resolved. I would have thought they should be on the case 24 x 7 until it was fixed. To add insult to injury I have subsequently received two emails from Sainsburys, one inviting me to use Click and Collect, the other stating 'We look forward to serving you again soon'. Evasive and incompetent are just two of the words that I would use to describe Sainsburys. They do not deserve our custom.
