FORD DOES NOT KNOW WHAT GOOD CUSTOMER SERVICE IS

How can ford have your car for 3 weeks. And simply give you no, courtesy car, because they did not have any available. I am so disgusted in the service received from Ford Kuils River. Had I or my husband not called every single day, then our car would most probably never been dealt with. We have our service history yet Ford Kuils River then comes back to say that someone else worked on our car. When they know good and well that the car was only serviced by Ford Diep River up until 80 000 km and then there after by Ford Milnerton. When we tried to claim, our car's claim was rejected because according the assessor apparently someone else worked on our car. Why would we allow someone else to work on our car when we know it would make our extended warranty on the car null and void. I am so sick and tired of the ****py service we have received from Ford. Your company claims to give good customer service but thus far, I have never ever received that.
