Mtn contract department incompetence and withholding of statements

I have spent over 3 weeks now trying to get a refund from mtn as I had paid my contract in advance for about a month. Called before the contract end date was not advised that I would need to cancel my contract as the 2 year period had ended. Called back in again only to be told that my contract had supposedly automatically renewed itself and that I had been charged, spent over 2 hours on a call waiting for a manager who apparently had been doing a call listening during this time. Only to be advised that I was charged for a pro-rata and that's why my fees where higher for the current month. Having to explain to her due to her incompetence that I'm calling for a refund not the charges. She set up a ticket and I was told to wait for 5 business days, called back again after this period only to find out that the previous manager hadn't included all the information by the agent. Provided further information to be told to wait another 5 business days. For when I call back during this period to be advised that I didn't have any money to be refunded. Now I'm asking for my acc statements so I can correct this incompetence using my bank statements they're not providing me with my account statements as mtn had miraculously decided not to send them to me via email anymore but still here I am empty had all I can say is I've had it and they wondered why I didn't renew my contract.
