Telkom, service provider with no service

Unfortunately the lowest review I can give is 1 star, otherwise, I would have rated them -5 stars. 8ta is my service provider and there is 2 scenarios I would like to mention. The first time I loaded R50 airtime in order to buy a 3Gb data bundle using *123#. The amount was deducted from the loaded airtime, but I never received the data bundle. I then tried to query the transaction, but hung up after being put on hold for more than 30 min. I decided to try a second time, in order to see how long it would take for my call to be answered. I placed my cell phone on speaker and continued doing c****s around the house, after approximately 4 hour someone disconnected my call without even answering, so I gave up. Last night I loaded another R50, again to purchase a 3Gb bundle, but was unsuccessful to even access the ussd menus. So I made sure my data connection was disabled. This morning when I tried again, I was able to access the menus, but received a message of insufficient funds so when I did a balance check, not only is the balance R0, but somehow I owe them R11 for emergency airtime. How this is possible without even being able to access the menus and only me at home, sleeping, I have no idea, "magic", and from first hand experience I know that trying to query this is a complete waist of time and would rather write of the loss than suffer through the same aggravation.
