Bad service

I have been handed over to multiple collections collections Agencies at the same time i have settled with the ine agency next day a diff agent calls me to let me know i still owe full balance!! NRB is Offering me now a 50 %discount giving me diff. Account numbers to settle. The agency Saya Recoveries have taken my money but they cannot acknowledge the proof of payment and was told they need confirmation from finchoice before thwy can send me paid up letter?! The primary company FINCHOICE legal is unavailable to get in touch with. After spending over R100 airtime calling. Their lines are constantly busy or just ringing!!!!!!
