Takealot refund

I had purchased a few items on takealot. I returned 2 of those items and asked to be refunded. It's almost 2 weeks now and I have not yet received my refunds. I have sent emails back and forth, Takealot claim they have refunded me. I sent them my bank statement to show I have not received my money back from them. They still have not responded. I like to shop at takealot because it is convenient, but I am truly disappointed on how the are handling this situation
