Worst ever promises that are not kept

On the 20th Nov I purchased airtime totaling to R20, via cell phone banking. My airtime was never credited and money went off my account. I called in and was told to send my bank statement showing the money did go off, which I did on the 24th November. I called again on the 10th, last week Thursday and one of their consultants assured me It would be credited within an hour. 7 days today, I called in the morning to ask, the first consultant dropped a call after keeping me on hold for more than 5min. I called again, which is my time wasted, and spoke to another consultant that now told me the matter is with their back office and I cannot speak to them, but he will send them an e-mail. I had to do emergency airtime, which costs me an additional R1 to pay back but it was not my fault. Please credit my airtime and stop taking people for a ride. The other thing is the bundles that I get every month on my phones, they just disappear within a day for some reason. Team leaders are also useless because there is nothing they can do also. I spoke to 2 of them and they were both clueless. Cell C is getting worse by the minute. I cannot wait for the contracts to expire, I swear I wont upgrade.
