No response after 2 logged calls and email

Good day , <br> Direct Axis has deducted my last payment as per a normal month but the actual amount was suppose to be about R300. I am now in credit with them with about R2100. <br> I logged telephonic calls and they reassured me that someone will get to me the same day to sort this out. 2 days after that I logged another call and the same story happened. I then mailed them with my query but haven't had any reply as yet. <br> I was a very satisfied customer and they only gave me good service so far. But it looks like when Direct Axis owes you money, the service stops right there. <br> <br> It will be greatly appreciated if have a look at this matter the soonest to sort it out.<br> <br> Thank you <br> <br>
