Refusing to transfer my funds back.

Had a guy come out via Ulta technologies to check my DStv signal on Sunday the 16th march 2025 and paid R1000 twice in error,now the 25 march 2025 and no payment made back,had several calls made to ultra to get the money,no payment made still.Sonnytime is the guy who did the work and got paid.now today he sends a R500 cash send and says he will send the other R500 when he has it.Sonnytime now states he lost his phone and can't access the app.i advised that any other phone can log in and make the payment.He calls me and says I made the mistake and that I just not threaten him,I said I did not threaten him.all I asked for was that the money be transferred today as he has it for over a week.This is very unprofessional and *********.I have been more than understanding and allowed a entire week to go.Sonnytime received the money but now it's excuse after excuse to get my money back.Sonnytime says his in Zimbabwe and there are not banks.there is a numerous banks there.I asked Ulta technologies to pay me and take it up with their agent but was told it will mess up their books.Shocking how people do this and think nothing of it.Sonmytime then states that I must reverse it,told him that I need a letter from him giving permission but he refuses to understand.Sonnytime has the audacity to blame me for making the error in payment instead of paying me back my money.says alot about the company and staff working there.no morals or ethics.first and last time using this company.
