C-Fibre , not responding Pathetic service

On 30 October 2018 , I sent an email to C-fibre Support informing them of my intention to cancel my contract with Cell C Fibre giving 30 Days notice , to terminate my contract on 30 November 2018. I was assured by the call agent after having sent the e-mail that the service will be ended.By 1 November 2018 , No response to my e-mail, after making another call to the support line I sent a further e-mail requesting confirmation that my Fibre service will be terminated on 30 November 2018, needles to say but by 6 November I still did not get any response or feedback that it has been cancelled. I phoned the call center again and followed up by an e-mail reqesting confirmation that the service will be terminated,No response to this e-mail received and a further e-mail was sent on 12 November after having phoned the call center again and needles to say that confirmation to my request has not been received . After all this the call center informed myself that they do not have any record of my e-mails etc despite the fact that I have requested them to annotate their records pending receipt of my e-mail. Before any one ask the e-mail addresses used ********** ********** " It seems that nobody is attending to the e-mails and repeated requests falls on deaf ears. This is pathetic for an organisation like Cell C. What is the point in asking for confirmation of request by e-mail and thereafter nothing happens?
