MTN does not respond to my emails

My previous email is below.<br> <br> ---<br> <br> Dear Sir/Madam,<br> <br> I am currently overseas and am not making use of my MTN contract. <br> My contract came to an end 6 months ago but you still continue to bill me. This is dishonest. <br> When I enquired about this through email I was told that I need to phone in but I have tried +27 83 1 808 and it says the number I have dialed is incorrect. If you want me to phone in give me a number that works. <br> I make phone calls back home to South Africa all the time but for some reason I get through to MTN and it says in a that recognizable MTN voice \The number you have dialled is incorrect."<br> <br> Please give me a land line I can dial so that I can cancel my contract with MTN for good. <br> <br> To reiterate - I have not used my phone for months now but I am still getting charged. <br> I am getting no help from MTN to cancel my contract and I feel this is dishonest. MTN is happy to bill me every month even though I am not making use of the service. <br> <br> <br> If I get no luck I am going to post on Hello Peter. <br> <br> Regards<br> J... <br> """
