Bad online service ok furniture

I made an online purchase for a pressure cooker last year. I canceled my purchase. I sent the online team all proof they asked for. They said money will reflect in 7 to 14 working days. Its been months. After I made enquires as to why I am not getting my refund they say I must go to the nearest store. I dnt see why I must do so after their commitment to pay me and i have proof in an email where thry said thry will refund me the money. As they asked fir my bank details. I didn't buy at store. It was online. I have been waiting since jan/ February for my money
