Telkom unable to help client

In the morning 00:00 around there of 28th jan 2019 i accidently loaded R100 airtime on ********** 073 instead of my number ********** 073 when i noticed it i called telkom customer service directly to let them know about it but they are unable to help me they said i must call that person and ask them to load my airtime back on my number best of all is that number is still off who says its not a data sim in a modem that you cant call??? I just really dont understand how difficult it is to take my R100 airtime thats been load by accident from that number and put it back on my number thats really poor service if you cant transfer it. I have the proof the airtime ref number or what you want to call it really telkom all i want is my money back in airtime
