Refund not processed.

Last Sunday (29/10/2017) I made a payment for my online order using a wrong reference, after realizing this I made another payment with the correct reference. On Monday (30/10/2017) I called the call centre and spoke to Asanda who adviced that I should send an e mail requesting a refund to ********** which was done on the same day. Eight days later, I am still waiting for a response. Yesterday (06/11/2017) I called again and spoke to Avela at 16:45. Avela sounded like she was in such a hurry and just wanted to get rid of me asap. She said I must give her my cell number so that her supervisor can call me back as he\she was out of the office, I then asked her to trace my email to see if it was received...she told me to hold while she traces the email (without asking me any information concerning the email) after about a minute I asked if she needed my email address to trace the email she said yes, I provided her with me email address and I had to hold again. I held the line for about 5 minutes then I dropped the line. I am appalled by the service I received from the call centre and that of the department that has to refund my money. I JUST NEED MY REFUND NOT THE ****TY SERVICE IV RECEIVED S FAR.
