I've been trying to cancel my contract for month

I have been trying to give notice to cancel my MTN contract since May as my contract said i need to give 30 days notice.<br> <br> In May I went into an MTN shop and i was told theres no need to give a months notice as this contract will automatically be cancelled on the first, this was also repeated when i called the call center and tried to get it cancelled a few weeks later.<br> <br> Yesterday was the 1st of July which is the day i was told the contract will be cancelled but this morning I received an sms stating that my services have been reactivated.<br> <br> I no longer want this contract i don't even want the number i want it cancelled as it has expired something I have been trying to do for 3 months but i have received absolutely no help from the call centre a call that gets hung up after waiting for an hour,the mtn shop that tells me they cant do anything , the twitter account which nobody is responding to.<br> <br> MTN is not allowing me to cancel a service i no longer want,<br> I will not stand for it and it needs to be rectified!
