BAD SERVICE, BAD CUSTOMER CARE.

I ordered yesterday around 3 on the Pick ‘n Pay asap and it was said it will be delivered same day around 5-6 then after I paid it changed today which is the next day at 10 am I immediately called them with no response wrote many emails called them this morning to cancel the order but surprisingly they delivered the parcel and I don’t want it anymore I bought it somewhere still no response. I need my refund they are not answering calls nor emails.
