So Tuesday evening i used the pay at pump petrol and my card was declined twice. Why because Sainsburys took £100 transaction and then another £100. I wasn't even able to put petrol in after this on my card. No signs warning you that you could leave £200 worse off and not get petrol. I now have to wait 7 days for the pending transactions to drop off according to my bank, Sainsburys executive team were very unhelpful and blamed visa for this even though this was their pump in their store and said there was nothing that could be done. I asked how i was meant to buy my food shopping but they could not answer and did not care i have to cancel a health appointment with my Osteopath because i do not have the money. I will never ever shop in this store or use their petrol station again. No customer care whatsoever, as long as they make money they are happy. Very disappointed with them and i hope noone else has to experience this Trustpilot is committed to transparency.
