King Price has me stressed out

I had an accident on the 14th April, I have the option of a courtesy car, you would think that with them having a strict 30 day policy on the courtesy car, I would have my car back before the 30 days are up... wrong... my car parts were only delivered to the panel beaters about 2 weeks ago only for them to have delivered the wrong part... after so many calls and asking for an extension as this was not my problem, they have only extended it until today the 4th June... I am waiting anxiously for them to get back to me to offer another extension until my car is 100% fixed, courtesy car is due back at 13.30 today... Why is it that they have no problem with getting you on board, but to assist when its greatly needed it's a problem.. I am a sales rep and I need a vehicle in order to work... I cannot afford 241.00 a day out of my pocket to hire out a courtesy car, when they didnt get the correct parts or the parts on time in the 1st place.. I will reply with another review once I have received feedback from King Price... be it good or bad...
