Almost a month STILL NO REFUND

I purchased a ticket for DSTV Delicious Festival for the 22/09/2018 and instead of the 23/09/2018. I contacted Howler and I was informed that I must purchase a new ticket with the correct date (new purchase) and I will be refunded my initial purchase (minus the admin fee). On 18/07/2018 I received an email informing me that the refund has been processed and should reflect on my account in 7-14 working days.

On the 08/08/2018 I emailed Howler informing them I have not received the funds as yet, the person I was corresponding with insisted that the refunds have been paid, I had to send them my bank statement and only then I was told there was a technical error with the payment system (09/08/2018), the monies will reflect in my account.

I did a follow-up on 15/08/2018 on what is the time frame for the "re-payment" process, I was informed 7-14 working days. 28/08/2018 I still HAVE NOT RECEIVED my refund, the lady who responded to my email (Robyn/Robin) insisted that the funds have been paid and they "no longer have those funds". I sent them my bank statement again from the 09/08/2018 until now, even called my bank to make sure I wasn't making an error..... STILL NO REFUND
