Worst service

Last year October i purchased the data sim card, received delivery and when called in to activate it i was advised that the sim card was a batch of bad ones that MTN delivered and a new one will be delivered, till date no sim card was delivered and nothing was activated. I then get debited an amount of R1196 from my bank account with any notification, i called supersonic and spoke with Bethumelo Themba and she logged a ticket, still waiting over 7 working days and the ticket is still with billing, called back again and spoke with Thembilihle Banoza and was advised that the refund was waiting approval and the money will be refunded in my account within 24 hours, its been another 7 working days and now i called back again and was advised by Dudu Zwane that the ticket was still with billing and they busy working on my refund and she will send another ticket and i will have to wait another 7 to 10 working days. I will be contacting either the ombudsman or enca and report this *****, I will also open a case of ***** as i did not instruct anyone to debit my account and how can you debit and account for services that are not active. and mind you its the customers airtime and time wasted each time you call and wait on the line for several minutes. called today and spoke to Leseba Sema advised that he will escalate it to the billing manager and get the credit approved.
