Pathetic Inexperienced Service

On Sunday 23rd August 2015 my sons Vivo Polo which was purchased from Lindsay Saker Fourways under a full maintenance plan cut out whilst he was driving with various warning indicators showing. We had the vehicle towed to Lindsay Saker Fourways. The car was returned to us Wednesday 26th with us presuming the problem had been resolved. The car drove home fine but the next morning stopped again whilst my son was driving to college. We got the car to Linsday Saker Fourways again and have not seen the car since the 26th. We were told that there was a part required and that it would only arrive on Monday 31 August. On 1st September my wife received a mail stating that the part is not available. I contacted Lindsay Saker Fourways requesting to speak to the service manager but Ms Fletcher was not available. A Phillip contacted me but appeared more in the dark than the car. Lindsay Saker's inability to employee competent staff has and is causing a huge inconvenience and stress to family. To take a week to figure out a problem is pathetic. To ask a customer to help put fire crackers under head office is even more pathetic.
