MTN - unhelpful

My contract with MTN with expired on the 23 April 2013, deduction in my bank account was still continuing. I was informed that I was supposed to notify MTN a month before my contract expired, which i was not informed or warned by the service provider. I stopped using data and airtime long before the expiring of the contract.<br> On the 05 October 2015 contacted MTN that I'm terminating this contract and I want my refund since I stop using their services, data and airtime long time ago before even the contract expired. On that day, 5 October 2015, I spoke to Angelina ref *** and I asked to speak the manager who was in charge that day, he ( didn't take down his name) promised to escalate this matter for my refund to be settle. He mentioned that the turn around time was 30 days.<br> On the 24 Oct 2015, around 10:34 I put a call through MTN call centre to check progress status. the manager on duty that day, his name is Yoosef ( Cape Town Centre), he lectured me on the same process i was told before, later said he tracing all the communication related to my query, and he asked me to hold and he was transferring me to his desk, without knowing I was transferred to several agents.
