Lack of response

I have been trying to cancel my contract with MTN service provider since 29 May 2015 (on its end date( but was unable to get any assistance as the call centre agents were on strike. I then sent 3 emails and did not receive any feedback until over a month later. in the meantime I had spoken to someone at the call centre (reference number: ***) i was told i would receive feedback via email to confirm cancellation, when I did get feedback I was sent a form which was already filled in by another customer when I raised this the same form (filled in form) was sent to me for the second time.<br> I have since been paying for my contract an amount of R399 but was debited for R494 on the 2 July and have not been topped up for my monthly recharge which was due on the 14th.<br> <br> I am unsatisfied with this service and still want terminate contract but still keep my number. hoping you can assist me to solve this.<br> <br> Regards
