Worst service ever

I called on the 27 sept to load MBs on my phone, the Mbs were loaded, after i got off the fone , i recieved an sms that all my Mbs had been used up. I called back on the 180 number n spoke to Maurine who logged a case as she advised that the problem was with telkom n that the Mbs would be returned back to me and give the tech dept 72hrs to contact me. Called again on the 28th as my existing mbs had also disappeared, spoke to brice who adv he load a case directly to back office so i would recieve a call from them tmrw morning. I waited, still nothing. Numerous times i called telkom to resolve this matter. Today I received their bill, which includes the mbs i did not use, how they expecte to pay fpr this is ridiculous. I have been waiting for the stupid back office to call me for a month now. Turn around time is 72hrs yet im still waiting. You guys can wipe your asses with my contract. I will not pay for mbs i did not use. I called so many times and no one bothered to call me back. It's disgusting how i have to take this to hellopeter before anyone takes action. I also logged a complaint in Jan i am still to this day waiting for feedback
