Call Centre Agent Irate with me being Hearing Impaired

I got a call from a Call Centre Agent from Telkom concerning my two contracts, the one that will end in June and the one where I still await the cancellation confirmation. Whilst talking the agent was irate that I could not hear her, I informed her she needs to speak clearly, she acknowledge my request, however when I requested her to please repeat the reason for the call, she got annoyed and put the phone done in my hearing impaired ears. Telkom became nice tech savvy, however there human contact service is embarrassing, I would rather communicate with a computer then any of their "human staff". Its ridiculous that they have no empathy or patience for disabled customers, the agent did even ask for what i made out of the call if its a convenient time to talk with me?????????????. I get more satisfaction from buying a contract online then going to a shop. Because if this is the kind of service i get from 'humans'. I have patience with regards to my cancellation request, however there is few information available for what will happen when you cancel your contract immediately??. Ai ai ai. But i must say I really disappointed in Telkom for employing people who has no empathy. I can probably write an essay about Telkom, but what ever. This is th reason why i still having upgraded, and will not upgrade again at Telkom, Sho June cant arrive fast enough. Please sort out my cancellation case number: ********** 8. All i got was an SMS to say Telkom will contact me to confirm the concellation via email... NOO such email landed in my inbox, will we are all use to incompetence in SA.
