Airtime sent to the wrong number

Greetings I have a problem here someone bought R100 airtime for me. It's was mistakenly sent to someone else as the person typed 447 instead of 477. The person that received the airtime has not yet seen it as her phone is off and the consultant that was helping me at Telkom told me that the airtime hasn't been used. He tried to call service center and I was told to send proof that the airtime was indeed purchase. We did that and I haven't received any help. My worry and what makes me panick most is that once the person that received airtime has seen it she will use it and I won't receive any help as the consultant I spoke to said. He also confirmed that it's possible to reverse the airtime and send it to my number as long as we email him proof.

Please help i really need the airtime.

Thank you
