Bad service with no help and I want contract canceled.

Dear Retentions and cancellation department

I have called a couple of times and gave all the information that was required however you are failing me as a customer. I am trying to cancel the contract that is now on a mo th to month payment but I am been given the run around. Initially this contract expired around June. I am trying to have the contract canceled on Sim number ***. How possible is it that when I call the cancelation department to get a letter of confirmation that contract is canceled then this department transfers me to customer care for that? Customer care told me to contact the cancelation department for anything to do with cancelation and confirmation of cancelation. What kind of mockery service are you running here? We as customers are using airtime to have data Sim contracts canceled. We do not call on free minutes. Cancelation manager please can you attained to this because I tried to be calm however 1 of the stuff members became rude and arrogant. He had the audacity to tell me that I am abusing my right as a customer when I calmly questioned can't he see the information on the system. He said I am asking questions that are out of his scope of work. Please sort this out because really we cannot be dealing with stuff giving us the run around. I am hurt because this guy felt he could actually abuse me and I was really calm when I talked to him. I have had to speak to 5 agents of which 1 of them was really rude. If he doesn't want this job he must leave rather than be rude towards customers. Haibo singaphela
