Daylight Robert by Cell C

I had two contracts with Cell C 1 data contract 2 airtime contract they were both expiring in November 2017. Beginning of November I upgraded the data contract which never worked for me three days after signing the contract I called Cell C Ladysmith notifying them that I have a problem because that data is giving me problems. And I went to the store several times and I was advised by the Manager Suan that they will do an investigation and I can cancel my contract at no cost because I had no joy with my contract from day 1, said the Manager Suan. He clearly stated that they won't charge me anything On that data contract and he will ensure that I don't pay anything since I had no joy from day 1. I was calling them going to the shop almost everyday. On the 12th of December I went to the shop in Ladysmith gave them the router and the sim card signed the cancellation documents. On the 9th of January I was in hospital and I received new documents to sign from from my colleague which she received from cell c because they misplaced the documents I signed on the 12th of December. After sometime I called the shop checking on the status of my contract because they do not bother contacting customers and I was told that my contract was cancelled. I also called customer services and cancelled my airtime contract on the 28th of November which I was told it will be cancelled by 28th December. My problem is that end of December there is an amount of R798.31, January R472.11 and February R299.00, after the December deduction I called Suan he promised to do an investigation and contact me which he never did. Remember I said he promised to motivate that I don't get charged anything o my data contract since I never had any joy with it from the first day. After the January deduction I called him again he also promised to get back to me which he never did, I even made him screen shots of my bank account and sent him via WhatsApp one Saturday he decided to respond to me he tried to explain something that I did not understand, I then requested that he forward me documents that reflect how they came up with those amounts. He took pictures of the computer screen using his phone and sent them to me I told him that they not clear can he please send those documents to me via email he never did that, I sent him a reminder after a week but still he never sent me the requested documents. This shows me that someone is not or didn't do his job if I'm still getting charged for something I handed over to the shop in December. CELL C IS REALLY ROBBING ME I NEED ALL MY MONEY BACK THAT THEY CHARGED ME FOR THE DATA CONTRACT BECAUSE I NEVER USED IT WITH JOY AND THEY SHOULD KEEP TO THE PROMISE THEY MADE WHEN SUAN TOLD ME THAT I WON'T BE CHARGED ANYTHING BECAUSE IT GAVE ME PROBLEMS FROM THE VERY FIRST DAY.
