CONTRACT CANCELLATION

I need to cancel my contract. I went in store and filled in forms. Called the 808 call centre to check if the request has been processed, only one be told that there was no request logged from the store on my behalf. I was told to go back to the store, couldn't as I was at work, so I called I instead, only to be told that they are busy with clients and I should call back in 5 minutes. 5 minutes later I called store again and the consultant was rude to me nd told me they were still busy with clients. Am I not also a client?<br> MTN PLEASE CANCEL MY CONTRACT WITH IMMEDIATE EFFECT, YOUR CUSTOMER SERVICE IS APPALLING! <br> My reference is Request REQ:***
