Telkom Is Robbing Me Of My Airtime and It's not the first time

I bought R65 airtime from my capitec app on the 3rd of September 2020. I transferred R50 airtime to my other telkom number because I wanted to buy data. But then I couldn't buy it because it had increased. And now that I have money to top up the airtime so I can buy the data my balance is 0.00 on both my phones. And I should have R15 on the other phone and again R50 on another one. I have never called anyone nor send a single sms from neither of my phones. It's ****en frustrating to be spending money on airtime then the next things the airtime it's gone before you even use it. I want my airtime back. Now I bought R30 airtime because I wanted to top up on the balance I had so that I can buy the data, but I ended up buying for R26 only to be able to quiry my airtime. Im so disappointed in telkom. I'm actually thinking about using another network provider because it's in fact not the first time when they do this. I will definitely go for cell c or mtn. And I'll advice as many people as I can to do the same.
