Disappointed in the level of service

<p>I booked in my corolla for service on the 20th of March at new new McCarthy Toyota Richards Bay. They informed me that 1 coil pack was blown. Which they replaced. They said the car was fine . Brought it home but it still has a idling and starting problem. Then we immediately contacted the workshop manager who was kind enough to send the technicians to look at the car at my home. They informed that another coil pack was blown.we insisted that they take the car back on Wednesday 22nd because it seems as if the car has another problem. They picked it up today and drove it to the workshop dealership. They informed us that ANOTHER coil pack is gone. So we bought another one and fitted. I was called in the afternoon to pick the car up as they said everything thing is fine. I just drove it out the dealership not even 20meters and it switched. I told the branch to come take the car and check it again. I am now informed that 2MORE coil packs are gone. At a cost of R1700 each. I cannot keep on replacing coil packs without knowing what the fault is. And whether it really is the coil packs at fault. It seems as if the workshop does not know what they are doing. Servicing this car for the past 8 years at Empangeni Toyota and never had such a problem. Car is worse than when it went in for service. Very disappointed. The fault needs to found. I can't except this from Toyota Richards Bay.</p>
