Telkom Line still not cancelled....

I requested cancellation of internet and fixed voice line from Telkom, in May 2018. I received a reference number for the cancellation in May. After months of wrangling the service was cancelled. I just checked my account online today (26 September 2018), and I noticed that I am still being billed for the Fixed Voice Service, for the line I had cancelled in May. The charge is for "Closer Call Catcher: R9.84, Telkom Weekender Plan: R7.21, Telkom Line Rental: R200.74).

I checked my online bill, and noticed that I have been billed this amount since May, when the service was supposed to have been cancelled. I then contacted Telkom's 10210 number this morning (26 September 2018), and I was told that the service that they need to look into my account is currently offline, and it has been offline for more than an hour. I was asked to call back in an hour.....this is extremely frustrating, as the more I tried to explain that this is urgent, the more I get told that the system in offline, and there is nothing they can do...

I have been paying this extra amount for the past 4 months, and I have a reference number for the cancellation that was initiated in May this year. So disappointing and unfair that I just have to accept and wait, while I am getting all frustrated about the situation.
