No delivery and no refund

I ordered online shopping to be delivered on 3 March. They sent me a message on 3 March saying they had some technical issues and would deliver it late and would contact me to make alternate arrangements (still waiting for that call). <br> <br> At approx 10.30 pm the groceries were charged to my credit card (so would be out of fridges and rung up I assume). By 2pm the next day they were still not delivered. I called the call center and asked where my groceries were being stored. They told me in a fridge. I asked then what about the frozen food? She then said - no they are stored in a freezer. I asked what about the fruit? She then admitted that she had no idea and said she would get back to me. Still waiting for that call too. <br> <br> After 2 hours I phoned and cancelled the order. I was told that the refund would take 4 days. An hour after that they tried r to deliver my order - I refused it. The following Monday they tried to deliver my order again. Refused again (imagine how disgusting this food is by this stage)! <br> <br> I have now phoned twice more for my refund and nobody can tell me when I will get my money back!
