NO REFUND FOR TRADE IN

On 19 May I traded in an iphone at iStore Cavendish after purchasing a new one a week before. Oh, we had to go back a week later as there was no manager to authorise when we purchasesd the new phone. Remember each time we have to travel from Muizenberg to Claremont. We were told by the wonderful young gentleman that it could take up to two weeks to receive my refund. TWO WEEKS I questioned! He said they say that just in case there are issues but because I bank with the same bank as them, it could take two days. Now, the two weeks came and went and no refund. Then on Thursday, 1 June, a young lady calls to say they are having issues with my payment, can I please send my bank confirmation. I explained that I had already given it to the gentleman who assisted us originally. She asked for the bank account number where my debit order comes off. I explain that I am not able to send at that moment in time so she asked me to confirm verbally. STILL NO PAYMENT. On sunday, 4 June, we take yet another trip to the store and speak to a manager who promises us that we will sort it out the next day. No word from him on Monday. Tuesday, the young lady who called the previous week calls to say that they found the issue and they cannot refund into a business account. I explained that I did originally give my personal account but sent it to her again anyway. She promises that I will get my payment by the end of the week. On Thursday, 8 June, I also get an email from the manager saying they have sorted it out. It is now the 10 June and STILL NO REFUND. This is more than ABSOLUTELY RIDICULOUS. I need to take action!!!!!!!!!!!!!!!!!!
