Cell C stole my airtime.

I had a backup phone with R122.00 on a Cell C SIM which has recently been cancelled. On contacting Cell C, they told me that the SIM had been off the network for more than 90 days, which is not true. They also told me that the SIM had a zero balance when it had positive balance of R122.00. Now they are telling me that they cancelled it because I did not recharge the phone within 120 days. Why would I recharge with a balance of R122.00. The communication is with individuals who work according to a script, and I just cannot get past their ridiculous assumptions. My SIM had a balance of R122.00 and was not off their network for more than 90 days. Cell C are completely unsympathetic and as far as I am concerned have ****** my airtime. I have no other recourse but to HelloPeter them. So much for client service.
