Poor service from Cell C

I have a portable router WiFi contract with Cell C. Contract was due to end in March 2021, so in January 2021 I got contacted by one of the ladies who works at Cell C Carnival mall notifying me of the fact that my contact is coming to an end and that I can upgrade and that they are running new specials/deals at lower monthly installments. I decided to renew the contract on the basis that it will be a month to month contract and can cancel whenever I want to. At the beginning of March Cell C decided not to load data on my portable WiFi router and did not contact me to let me know, so on the 12th March 2021, I sent an email to the same lady who I had sent all my documents to and asked what was happening as I had not been able to connect since the 1st of March, as a result had to buy data from MTN in order to be connected. I got no response and on the 25th March when Cell C decided to take their monthly debit order, I reversed it since I cannot be paying for services not rendered. Cell C tried again to take their money and I still reversed it again. Then I received emails from them telling me of this non payment issue, I then sent them an email on the email address indicated on the email received, to my surprise the email couldn't go through, clearly they like taking people for a ride. I then went on their website to try make contact, to my surprise there is no customer service email, just the 6 digit number that requires a call using cell c or another service provider - meaning, they are expecting their customers to spend money on issues caused by them. Then I eventually managed to send them a message via the "call me back/contact me" dialog thing they have on their website, which does not allow one to write a full description of what the issue is. Fortunately a lady from there called me and I explained my issue, to my surprise she told me that the lady who processed my contract renewal information, did not finalize the process and that she could not see from the system why I cannot connect or why it says "connected without internet" and that I should go to the store where I took my contract and ask for assistance. I then called the Carnival mall store (another expense for something I did not cause), then found out that the lady does not work there anymore, explained my issue and was told I can only get assistance if I visit the store, told the lady I spoke to that I do not live in the Eastrand anymore and will not travel all the way for something they can fix via online/technological platforms. She then said I should go to the nearest Cell C store and they will assist. I then went to Cell C store at Northgate mall and the lady that assisted me was not cooperative and she couldn't answer any of my questions when she took the Sim card and put it on her phone and said she's checking settings. I asked her what had changed on the settings since I did not request any changes and did not change anything whereas the connection just stopped. I don't know what she did since she was not in the mood to helping, eventually it connected when I left the store. Then Cell C took its R214 installment which I had been reversing. I let it go because I was now connected. Then came end of April 2021, Cell C deducted its new installment of R122.34 but as of 1st May no connection once again. I went to their website and submitted in the short dialog thing that I now want to cancel my contract because I can't keep doing these back n forth thing with Cell C. To date 09 May 2021 I have not received any call or communication regarding my complaint and I am not prepared to pay for services not rendered and infact I want my R214 back since the whole of March services were not rendered.
