Worst service ever.

Hi, I am so disappointed in the customer support within Telkom no one knows what's going on all they can tell you is jargon words. They can't even tell you what the services on the system mean. As I had recharged with a 5GB free me bundle and to wake up the following day with half of this depleted. Even though the time frames are near impossible for me to have been active on the net. The one said I was from 9pm till midnight, then puts me in hold for over 30mins looking for answers. Second consultant says I was active from 7pm till midnight where I only recharged at 8pm. I purchase the same amount each month and this has never happened then I'm told it's due to fast internet, really. When I ask for a supervisor they all in a meeting apparently which we all know that's excuse #1. Then there is no seconds in command(2ic) which is even worse but I was told they wouldn't leave agent on own but still got the excuses I did. I would love this matter to be looked into and provide either valid proof or correct this mistake ASAP
