Bad service

Telkom Mobile stole my data yesterday the 21 of January 2019, I bought R10 Time- Base data which amounts to 150MB the an hour and half later I decided to add more data and I recharged with R100 then exchanged it for 1GB at about 14:13 pm but that data vanished within 15 minutes. I never used it and the reason I was aware that my data is gone was the sms they sent, usually they update me on how much data I’ve used and how Moluccan is left but yesterday there were no notifications. When I called their customer service department I spoke to Yamkela, Thandi, Mpho Sphumelele but to no avail as they didn’t even know what is going on or how they should respond to the issue at hand and I later spoke to Morris who tried to assist but was also defeated in his efforts because the so called supervisor Charmaine Ma***o refused to come to the phone and address the issue as well. My first call was at 14:31 when I received the sms until around 19:58 pm holding to be transferred to Charmaine who plainly disregarded and disrespected me as a client and knocked off knowing fully well that I’ve been on the call holding for her. Mpho and Morris the consultants I spoke to said Charmaine was in a meeting, later on she said she’s on lunch and she said Charmaine is assisting other callers while I was holding for her. Later I got hold of Sibongile Malinga (Supervisor) who tried her best to assist. I would have failed my exams that were due last night because Telkom stole and refused to re-emburse my data. They all told me to wait 72 hours before my query could be looked at and they can’t help me.
