Shocking service AA South Africa!

My car broke down and as it had missed a service I called the AA foe advice. They recommended Kohler motors in Claremont, as it was an AA approved vendor. My quote went from R3000 to R24 000 to R50 000 in the space of 3 months with no progress made at all. almost 5 months later the car is still in pieces on the Kohler motors workshop floor with no resolution in sight. I contacted the AA for help one month ago.My feeling is that in the best interest of their vendor,they're looking for a loophole and stalling me. I've had NO update on procedure or status of my vehicle. The AA NEVER responds to calls or E-Mails.
