Cell C Poor service

I have had a Contract with Cell C for two years. I received an email on the 30 November 2019 informing me that the Contract will be coming to an end on 29 January 2020.

On the 27 December 2019 I called their call centre 084 145 and spoke to an agent that then attempted to transfer my call to cancellation department and also gave me their 084 143 contact number. Immediately after transferring the phone dropped. I then called the 084 143 number, which kept on telling me the number does not exist. After several attempts between landline and cell I called the 084 145 number and explained that the 084143 number is not going through, The consultant (different one) wanted to try again but I explained that maybe she should try and find out from a manager what is going on or allow me to speak to the manager. She went and spoke to the manager and she got back to me and explained that I should call on the 6 January 2020 as the Cancellation Department is closed. In disbelief I visited a Cell C store in Victoria Road, Pietermaritzburg and spoke to a Consultant that advised me that the department was closed and that I should call on the 6th. I tried calling today on the 7 January 2020 and finally spoke to the cancellation department, The consultant explained that they had in fact been working every day except on public holidays and that I would have to pay for another month as I did not meet the 30 day notice agreement.
