Terrible Service provided by Cell C

I have had a contract with Cell C since 2011, which at the time was taken out in my mother's name. In 2021 my mother passed away and in order to take the contract over I attended multiple Cell C branches and submitted the necessary paperwork in order to effect the change of ownership. This never happened despite the numerous submissions of the requested documents. I then received a message from Cell C stating that the contract had been terminated successfully as requested, despite this not having been the request. The number is used for work and all my clients have the specific number saved. I currently am unable to make or receive any calls. I attended another Cell C branch to ascertain what the problem was and if I could reactivate the number and have it placed on pre-paid. I was informed that is is not possible and that I had to contact the same divisions to whom I have been sending the necessary documents to. The service has been terrible and would not recommend Cell C to anyone. I am yet to receive any feedback from Cell C.
