Disappointed customer

I am very disappointed with MTN customer services, they don't seem to know or understand what their doing, This is what happened, last year November I took a one year contract home Wi-Fi with MTN, Received a message early September that my contract is ending on the last day of October. I called the customer service it was on the 16 September to cancel my contract and I was advised to call on the 1st of October for 30 days notice. When I called them on the 1st October I was told that I will have to take back the router to the nearest MTN shop and get a something number to cancel, they don't do cancelations for the routers. I went to MTN Galleria Mall and I was told they don't deal with one year contract ,they only deal with month to month home routers, and we called the customer service while I was still at the MTN shop but we didn't get through, Now I am stuck with a router that I don't need and will debit my account month end.
