Continued billing after contract cancellation

Good day<br> <br> I cancelled a 2GB Data contract ***) on 28/02/2015. I have the cancellation documents that proof this. However, MTN continued to bill me for this for April and May. Resulting in a supposed R238 arrears on my main account. WHICH I REFUSE TO PAY AS I CANCELLED THE CONTRACT IN FEBRUARY!<br> <br> I logged a complaint call on 19/05/2015, the reference nr: *** during which the call center agent ensured me that the contract has been cancelled (reference nr ***) and the R119 supposedly outstanding voided.<br> <br> After this, MTN still suspended my main line. I cancelled it for the THIRD TIME: with reference number 128 773 405 on 02/06/2015.<br> <br> As of yet, my cellphone number ***)has been reconnected, but NOT this line's mobile data AND my latest account still shows an outstanding amount of R119 for April and May= R238. <br> <br> I also emailed this complaint to MTN's 809 email on 11/06/2015 and have not received a response. <br> <br> Please can this matter be seen to urgently or I will cancel all contracts with MTN and move to a more efficient service provider. <br> <br> Thank you<br> Coba-Maryn Wilsenach
