Exremely frustrated with telkom for cancelling services without my autorisation

My telkom services was cancelled without my authorisation. I went to a telkom store to enquire. According to them it is alledged that i contacted the call centre and requested for a cancellation of my telkom services. I was told that i called on the 10th January 2018 and spoke to a"Yamkelani Ndondo" requesting for a cancellation of my services. I was even given an order number. I told the consultant that I had not requested for a cancellation and asked for the recordings to prove this. I was told that they cannot cancel the request for cancellation. I am concerned as i suspect someone is trying to **********ly get me to pay for reconnection when I had not requested for cancellation in the first place. This is a serious inconvenience as I cannot make calls or use Internet.
