Sainsbury's online delivery used to be good - I have been using it from the first lockdown last year. However, yesterday's delivery, expected between 9-10 pm failed to turn up - no text or phone message to explain why it did not arrive I tried phoning Sainsburys customer service, waited nearly an hour - the guy who eventually answered said he would find out what happened - waited a further half hour - then my phone ran out - but it was past my bedtime anyway so gave up. Had email this morning to 'confirm that my order had been cancelled!!! I did not cancel it - Sainsbury's did that without an explanation. I phoned Sainsburys customer services again who told me it was due to technical difficulties. The customer service assistant did apologise profusely, so I cannot find fault with him. I understand now (from Google) that 10,000 customers have also been affected by these technical difficulties. Not good enough Sainsburys - the only reason you got two stars is because I have been happy over the last year but the way you handled this is completely unacceptable.
