It's been 3 months now...

I have not received my paid-for data/airtime for the third month in a row, the first time my cellphone was put on a top up data plan without 1. informing me and 2. I still had a year left on my contract, the second month they sent me a statement saying that they have been sending my data/airtime but that I have a **** on my phone that takes R5.00 a day, first of all if it's R5.00 and the month has 31 days that gives me a minus of R155 minus my 500 mb that gives me a total of 345 that I should still receive, but I don't, one of the staff members gave me the number that I should use to stop the "**** messages" (30333) the problem is that this number is for Vodacom users only, if you work on my cellphone contract, you should know that I am not using that network. I have not received any feedback even though I did stop all my "**** messages" and I still did not receive my data/airtime, for 3 months in a row the data that I have been supposed to receive now builds up to 1 500 mb, I hope you're willing to pay this out, as that this was not my fault, but yours.
