Worse service ever

Good day ,

I have a data contract with Cell c which I took more than a year ago , due to financial problems and with employment I decided to cancel my contract as I knew I would not afford it in the next coming months. I called Cell call centre in November to cancel and was given the amount I must pay as a settlement of the contract which I paid and sent an email stating me intentions to cancel . in December there was no debit on my account which obviously assumed the cancellation was done as requested. in January I got a debit again and I called in to lodge a complain and explained my situation and was assisted by Nurse from retention and she was honestly very helpful and called me for 3 days straight and sorted everything and contract is cancelled said to me someone from billing will contact me and they did and the person was asking me to send emails again that I already sent to Nurse so basically this person was starting the process again asking me when did I cancel the contract it was so frustrating because I am starting over again and again I sent all the evidence emails and copied in retention and since that day I had no reply , no call nothing ,. instead this month of February I got a debit of R500 on the 25 and then again on the 26 I got a debit of R520 so my contract is still active worse part about all this is that the device stopped working 6 months ago its sitting on my desk and hasn't been switched on for that long so how do they even bill me , where are these numbers coming from because the debit must be R299 ,

I am so fed up its unbelievable how badly you treated me I had a similar situation with Vodacom where I cancelled the contract and was assisted and everything done in two day so how come its so difficult to do the simplest thing , no matter what I will never trust your brand or come back as client especially after I told you about my financial situation you still didn't even show compassion

please cancel that contract with immediate effect and stop debiting my account
