I want my refund

Incredible Connection has a stinking customer service. It's almost 2 months that I have been requesting for a refund. I bought Dstv Streamer online on the 15th of June. The order was supposed to be pick up from the store. 2 days after the purchase I noticed that the order is still processing I canceled and went on to buy the product from the store. I requested for a refund a week later they asked for my banking details, I sent the banking details 2 times. I even contacted the customer care line after I have been going back and forth with the store manager in Greenstone Store. I was told the matter has been escalated. I haven't heard from them since then. This means if I don't call them I won't get my refund. Incredible Connection owes me money and they are not doing anything about it
