Payment arrangement = FAIL

I have recently been handed over to Ver-tex solutions by Capfin for not being able to pay for a loan that I had taken in 2021. I had a consultant from Ver-tex call me 21/06/2022 in order to make a payment arrangement to pay off the loan amount and after coming to a agreement I was advised that I would be getting all the necessary information sent to me via email and I can start making payments as from the 28th July 2022. As soon as I got off the phone I sat and waited and checked my email over and over again. It is now the 22 June 2022 and I have still not received a single bit of information from the consultant that contacted me. This is absolutely unacceptable. 1st the people from Capfin barely tried to contact me. It's like they seem scared to speak to people that owe them money and now the people from this company can't seem to assist at all. 1st call that came from this company was to my girlfriend and not even me! HOW AM I SUPPOSED TO PAY IF I DON'T HAVE ANY BANKING INFO AS REQUESTED?
