Migration from Contract to Pay as you Go

My one contract from MTN was supposed to stop on the 23rd of April 2015, after which I sent MTN an e-mail, kindly requesting them to change this contract to Pay As You Go.<br> <br> I got an e-mail back saying I should request this in writing but in the meantime the contract will go on on a month to month basis. I asked them whether my e-mail requesting this is not clear enough!?<br> <br> Obviously not.<br> <br> Needless to say, from April, I am still billed on a month to month basis, regardless of my numerous e-mails to them.<br> <br> MTN Customer Service STINKS! I will NEVER upgrade with them EVER AGAIN!!!!<br> <br>
