Money paid in error into home choice account

I mistakenly paid R5020 into a Homechoice account and have sent the company emails to refund my money as i am not an account holder and the money was paid in error. I am frustrated because no one seems to get back to me, when calling the customer care line it seems as if no one is able to assist. I have sent all that they had asked me to send but up until now i have had no response from to say when my R5020 will be refunded back to me. I am extremely disappointed with HC!!!!
