extremely bad service delivery

I sent my vehicle in for repairs close on 2 months ago as the vehicle was no longer driveable. Since then i have had numerous promisses made that they would get back to me as soon as possible which never happened. Finally today after numerous phone calls again they acctually managed to contact me back only to tell me that they have now realized that there are no parts available in south africa so i will now be forced to sit without transport for a further minimum of three weeks! Totally unacceptable if you ask me!
