HOW CAN I GET MY ADD CONTRACT CANCELLED & PORT

My additional cell contract *** termination date was 2015-09-18. I gave notice ref nr *** to <br> cancel to contract and port the nr to Vodacom because of the bad reception in our area. Since then a phone the Service Centre on 13/10/2015 and spoke to Sanelisiwe Mbitse who send me and email which was forwarded to MTN retentions Escalation Dept. Afterwards I phoned the service centre twice who informed me that the number<br> is terminated and the contract is cancelled and the cell is pay as you go. Yesterday funds were loaded again on the cell. I phoned Service Centre again this morning and spoke to Lebogang Mobeke which informed me that <br> the contract is not cancelled. She send an email to Nwabisa Mjokovana at escalations to CANCEL THE CONTRACT. In the meantime MTN is making money out of me. Good heavens MTN I cannot pay for your mistakes and penalties. Must I report the matter to the ombudsman if funds are taking from my acount again but they are as bad as everybody else.
