MTN trying to score axtra

<br> I cannot believe the incompetence of MTN that they cannot resolve a simple matter?? For two years they had no issue in getting my EFT allocated to my account, but now that I canceled my contract, they cannot allocate my last payment?<br> <br> On 17 April 2015 I made a notice to cancel reference on *** that was assigned to Thembekile Mathopo and received confirmation of cancelation on 22 May as per 30 days' notice and was advised to pay invoice dated 13 May 2015. This invoice was paid on 31 May 2015 and proof of payment supp****.<br> <br> To this day I am still getting billed and I noticed that is almost R700 owed for something that I have not used since cancelation.<br> <br> All I ask is to please remove this number from my name as per above cancelation and payment done as per the agreement.
