Cannot Contact Anyone - expired contract

I have been trying calling the call centre since March to terminate my data contract and I have had absolutely no luck with anyone answering the calls.<br> <br> I then decided to send an email to Customer Care (dated 19 March), finally on the 16th of April I got a response and a reference (note that it took just under 1 month to respond!)<br> <br> I am still being debited for this contract which as been cancelled and I once again cannot get hold of ANYONE at MTN and staff are unable to assist in store - WHAT ARE WE MEANT TO DO! <br> <br> This contract has been nothing but a nightmare the entire time!
