Never, ever shop online with Sainsbury's. Firstly they missed out 2 items from my home delivery without telling me or offering a substitute (clearly 4pts of milk and some Greek yogurt are tough to find subs for), despite emailing in the morning saying everything was in stock. I decided to do an online refund claim to save me calling them. I asked for the cash back because a voucher is useless if I don't intend on using them again. It then says they have to call you back to do it over the phone rather than putting it back onto the card you paid with. Fine. However 4 days later I get an email with a voucher code on it. I therefore have to call them up and spend 12 minutes on hold to get through to someone called Nadia who takes my details but can't actually help. She says she'll transfer me to the refund team but then manages to cut me off! I then have to call again (15mins on hold) and finally speak to someone else and then get transfered to the refund person (a short additional hold) who finally took my details and I'll get my money in 3-5 days, at least a week after they took it wrongfully in the first place. Never will I use Sainsbury's delivery again.
