I accidentally bought airtime with internet banking to a wrong number & I would like to reverse it.

I accidentally bought airtime to a wrong number & I would like to reverse it.

On Saturday (04 April 2020) morning I called Telkom and an agent promised that once her team leader approves, it will be transferred to the correct number within 24 hours.

On Monday (06 April 2020) a different agent said I should email her team leader my proof of purchase and it will be transferred within 24 hours. (Did you?)

Tuesday a new agent said my cases was escalated but doesn't see the reasons, she decided to fill in a new case and while we were busy communicating and working on it for more than an hour she just hang up haphazardly.

I Called her twice and she picked up in both occasions, once she heard my voice she hung up, 3rd call was picked up by a male person who was talking properly to me and willing to help with my cases. But as soon as I mentioned the problem he knew me already and just hung up.
