Poor WCA service on hearing loss claim

I have a hearing loss claim that was approved almost two years ago but the feedback from WCA is - Payment has been captured - waiting Finance department. I had to resubmit my documents twice in the last 5 years by the head office in Pretoria, I have a record of 199 e-mails between myself, WCA (COID) and my ex employer with to date no resolution, just the one delay on-top of the other. Documents being signed for but disappearing and then I need to resubmit
