Cancelled contract in Feb but money still being taken from my account

I had a 24 month contract with Telkom ***) and attempted to cancel it after 24 months had lapsed.

In January 2020 I went to the shop (Telekom in Liberty Mall, Pietermaritzburg) to cancel and was told to do it online. I tried doing it in line with no luck. In February I was assisted by a friend to do it on the Telekom app. On 5 February 2020 I successfully concluded my cancellation and got case ***1 for cancellation. I also got notification that someone would call me to finalise my case. Instead I got calls where I was offered upgrades and all sorts of Telekom products. I explained to the agents that were calling me that I was expecting calls pertaining to my cancellation. From the day of my cancellation, my modem then displayed a red light and no longer a blue one. At the end of February I was charged. I didn’t understand how because I had already cancelled. Also at this time I had taken a Vodacom contract and was now using their dime card after having noticed the Telekom one was no longer working “red light instead of Blue”.

On 03 March I got a message that “my query will be attended to” with case number *** I then waited to see if they will debit my account again which they did and I reversed it.

On 23.03.2020 I started getting messages that my payment was overdue and that I should pay R355.13 this went on that every month they debit me and I reverse the debit order.

I got messages on 20 April 2020 and 26 May 2020 that “account for customer ***” has been suspended due to collection”.

I then went to post on Telkom Facebook page on 02 June 2020 and was contacted by a lady who works at Telkom and I sent her the screenshots of the reference numbers I quoted above and she rep**** that “please send that screenshot and the reference number for cancelation if you have I'll manually cancel on the system and escalate to the billing department for a dispute with the reference number”. She confirmed that she could see that my line was cancelled however my line was still at billing Dept for collection. She was going to escalate it to her manager and give feedback.

On 03 June 2029 I got a message “your query will be attended to. Your case number is ***2”.

On 19 June 2020 I got a message that “my case number ***2 has been resolved” I thought this is the end of this matter. I also want to mention that from submitting and until getting the “resolved” notification no Telkom person called me, except the lady that I had sent the screenshots to. She gave me feedback that she got was that “I had to pay because I used the services” so that is the problem I’m still having right now because Telkom insists that I have to pay even though I cancelled on 02 February 2020 but they continued to debit my account.
