Refund

Goodday. I canceled my contact received my last statement with a R150 credit. I put in a enquiry on 23 June 2020 and again 15 July 2020. I again called today 30 July with the same answer, my enquiry has been forwarded. I ask to the refund department directly and was told I can't... My phone calls and message for this refund will at the end be more than the R150.
