Very disappointed customer

Had a shock of my life on Monday, I bought R100. 00 airtime, then bought 1GB bundles +1GB night suffer, as soon as I was done I quickly transferred 100MB to my other telkom number and then switched off my DATA, I was then left with 900MB and 1GB night suffer, when I woke up the next morning, I noticed that 8minutes after I bought that Data (a night before) , I received an sms saying my data was dipletted(finished), shocked as I was, I then called telkom, spoke to Fine(who was polite) whom assured me that she logged a query with ***,she said she will then call in the morning to do a follow up with me as what happened was an error,SHE CHECKED AND CONFIRMED ON HER SYSTEM THAT WHAT HAPPENED WITH THE 900MB+1GB NIGHT SUFFER DISSAPPEARING 8MINUTES AFTER BUYING THEM WAS NOT RIGHT,now the problem is she never called back as promised, IV been waiting ever since, no one called back and when I try calling Telekom myself, my calls get cut off after the introduction tone,... "It says press 1 if you need help from the number you calling from and after I PRESSED 1 or any other number ,IT KEEPS SAYING I DID NOT PRESS ANYTHING until am cut off " IV HONESTLY HEARED IT WITH TELKOM, I NEED THEM TO RETURN MY DATA(900MB+1GB night suffer) OR MY CASH, WHEN THEY'VE DONE DOING THAT, I'll use what I have, when done, I'LL CANCELL ALL THE THREE NUMBERS I HAVE WITH THEM, THIS IS CALLED ***** & is not the first time is happening, last week my 50MB disappeared, then 35MB as well, when I called I spoke to a lady who promised to transfer me to her manager and then SHE LITTERALLY CUT ME OFF, she was rude and did not listen to HELP BUT RATHER TO RESPOND
