SHOCKING CUSTOMER SERVICE!

I did not receive my airtime for July, even though the debit order went off my account.I phoned customer services & they told me to wait 24 hrs & it will be loaded. I waited 24 hrs, still no airtime. I phoned the call center again & played the MSG to them where Altech keeps telling me to top up my airtime. I was then told it was an issue with CELL C & I should wait over the weekend & I would get my airtime. By TUESDAY, still no airtime. I have even called the call center & had operators PUT THE PHONE DOWN IN MY EAR. I have had to use over R 100 in prepaid airtime trying to sort out this issue & still, my monthly airtime has not been loaded. I have had to make use of the company phone to try & sort this matter & I have to pay this money back too. Altech is very quick to take my money every month & what service do I get? NO AIRTIME & operators PUTTING THE PHONE DOWN IN MY EAR. What makes it worse,is the operators tell me they CAN SEE that I have NOT used my R 100 airtime on the system - EXACTLY!! how can I use something I DID NOT receive?! I am paying for a service that I am not getting....this is theft! Your customer service is APPALLING! I'm disgusted!
