pathetic customer service

This is the 3rd review I am writing about MTN. On the 1st of July 2017 R565.38 was deducted from my account for no apparent reason because I am currently a prepaid customer. I was promised that my money will be retured to me within 5 working days. After conversing with 4 mtn staff members who kept on apologizing to me and saying that my situation will be sorted out immediately, 35 days later my money has not been retured to me. R565 is alot of money. Firstly Mtn shouldn't have deducted any money from my account without informing me in the first place and secondly my money should have been returned to me in 5 working days. I have been a loyal customer for 11 years and but you have just lost a customer. I will be taking my business to another service provider. For a customer to beg for his rightful money back is very pathetic customer service. I want my money retured to me immediately before I publish this article in the daily news and I take this matter up to consumer watch and let the whole of South Africa know what pathetic customer service Mtn gives to its customers.
