Customer Service is disappointing.

I ordered blankets, did a cash deposit. By mistake I paid a R1000.00 more. From the day they called confirming that they received the payment. I have been asking for my refund and every time I call I am put on hold or they cut the call. The names I can remember is Siphokazi and Zizipho. Zizipho gave the number for processing whereas she said she was giving me their Finance team number. After stating my case for Lord knows many times no one is willing to assist. I have a ****ing coming up and every cents counts. I very disappointed and most of all I need that money back. My order number was ***8.
