contract cancellation over charge

I am very disappointed with the service i received from cell c. I took a contract last year for a Mobicell device and wanted to upgrade it after 6 months so i can get a better phone which was a Huawei p smart simple as that. However that was the worst night mare of my life had to speak to almost 5 different people i even went to the cell c store but there is no solution i am a frustrated customer i was charged twice for a cancellation fee i have to suffer for someones mistake or miss information. Cell c is the one hiring people that are sleeping on the job or not providing enough training they should pay me my money back Instead of paying R 199 for a contract this month i had to pay R 730 this month because of someones mistake. on top of that and i have paid R532 for a cancellation fee. my account is a mess. And to show that i am a loyal customer even after the horrible service i received i still take another phone with them (samsag j4)i am very angry because i wasted my time speaking and explaining something they should have record of and lost my money and there is nothing no one can do about that i spoke to Ntokozo now who is apparently a supervisor he still does not understand my problem nor can he solve it. I want to be contacted with a solution i dont want to be asked questions as you guys have my details on my system i want my R532 paid Back to me .This is very poor poor service i am upset i dont have money to just donate to cell c just for the sake of it or for fun, i am not willing to answer any more questions i need a solution and that is my money back i dont want to speak to another supervisor or agent who is going to waste my time i need cell c to investigate and pay me my money today or i will have to take this to consumer protection act or the Ombuds man
