Empty promises

Every since I have been part of MTN I have recieved the poorest and worst treatment as a customer loyalty,this is from call center level, to branch level, I went for an upgrade with mtn, from being a Nashua Mobile client where I never recieved any problems. Now I'm being billed twice on my contract, which was not the agreement when I signed the contract, I went to Westgate branch and spoke to the agent that assist me, he advised that the problem will be sorted, the following month it was not resolved, I went to.see the store manager who could not even solve the problem himself.MTN has the poorest customer service.I will escalate this matter further.<br> <br>
