Vodacom account **** with Ramatshila-Mugeri (Pty)LTD

I took a contract with vodacom, failed to pay the installment sue to financial circumstances in 2017. Change of jobs. They then sent my account to Ramatshila-Mugeri(PTY)LTD. I started paying vodacom though them. In 2019 I received a call from another company Banadits stating that my account worth vodacom has been moved to them. So I need to start paying them going forward. What was strange was the bill I had paid to Vodacom and to Mugeri. They had no record of it so I have to start paying from scratch. When I phoned Mugeri (Pty) Victoria handled my case last year November, she always come up with excuses like they offline she will call me again but never do. Phoned again in December spoke with Anastazia.she also said the same thing at first they offline. Admin will call me on monday . Bever hear from that admin until I phone again. I have been paying my account but no one seems to have a paying track record. All they want is keep asking for more money.
