Cancelation and refund

Sale was finalized without my authorization, router didn't have signal in my area. Logged a case investigation came out in my favor, cancelation request was logged. No communication given, have to constantly call for feedback. Was promised a refund 1 month ago, consultant told me to call mtn. MTN said that I owe the R2300 for cancelation fees, Mondo claims that they will pay it so mtn can stop trying to debit me but mtn continues to try and debit my account. This is long overdue query should be closed, contract canceled and customer refunded. Not forgetting to mention just how rude the call centre agents are. No one cares about the customers frustration
