Poor service, poor communication, poor parts availability

I have never seen such an unprofessional and poor service, i took my car for assessment beginning of AUG now its October waiting for parts, imagine a common car NP200. They send out a communication that parts have arrived and you wait another 3 weeks to repair. They are unreachable on their lines 80% of the time. I requested for a towing they said they don't have a tow truck in the last minutes, when i told them earlier. I had to inform my insurer to change a panelbeater after waiting for over 2 months
