I would give them 0 if possible. My home delivery was supposed to be £85.00. Sainsbury's took £135.00 out of my account!! I was told - as a result - I would be given a £93.00 voucher within three days. When the voucher arrived, it was £48.00. My own money turned into a Sainsbury's only voucher, which Sainsbury then tells me what I can and cannot spend it on. This is Sainsbury's policy, apparently, and it cares not what the customer thinks about it. After 5 telephone calls, I was told Sainsbury's would refund my money back to my bank account. After a 59 minute call with Kirston, being put on hold twice, I was then informed this could not happen after all. Extraordinary experience. I will never use Sainsbury's again, and that is my policy, and I care not what Sainsbury's thinks.
