Cell C

I have been with Cell C for at least 15 years renewing my contract every year. In November last year realising that it was almost time for an upgrade I went into the Norwood branch and was told I could upgrade immediately. This i duly did stating that I could not pay more than what I was paying for a Top up account. This was agreed upon and I got a new phone. When I got my account it was much more than I had been paying and went in to find out why and was told it was a once off because of the change of phone. I understood and that amount was paid. Every month thereafter I paid the original amount. Now I get a notification that I will be paying R498 at the end of may as apposed to R298. I phoned and wrote and was told this was because of my upgrade which was from April. I was convinced they were mistaken because I had already paid the extra and my upgrade was not from April. I told them this was impossible but they are still insisting I pay. I am a senior citizen and cannot afford the extra payment and am convinced I do not owe it. As it is a debit order they will just take it off. Unfortunately my contract still has more than a year to go but when it is finished I will definitely be finished with Cell C.
