*****, Accounts, and bad service

My first contract with Cell C was a breeze, and made me decide to take out another contract with Cell C. With the second contract a month later I realized someone stole my identity and used it to take out a contract falsely under my details at vodacom. Luckily vodacom sorted it out and told me I am not the only person that got hit from the same Cell C branch, Cell C never even contacted me, Ever since I started there every time I got a statement via email, my balances showed zero, all the details are on the statement but numbers show zero. The last invoice I received was in May, that is 5 moths later. How do you expect your clients to keep track of their financials with service like this??? I always thought Cell C was a good network, but your service is getting worse and worse. I can't even go to a branch to sort anything out, I have to call for anything. I decided to cancel my first contract in September and took the necessary steps, still they phoned me in October asking if I want to upgrade because I am due for an upgrade(is there any internal communication at Cell C???) I always though good about Cell C, but these past two years been a constant head ache! waiting for response.
