Money leaching *****up

If I could give no stars I would. I went to get my car serviced and everything went well. I booked my car. Payed for the service afterwards and was on my way. Until my car started making a squeaking noise 4 DAYS AFTER THE INNITAL MAJOR SERVICE. This caused my cars' engine and handbrake light to flicker while I was driving. I had to take my car back only to find out that my alternator belt was scratching against my time belts' casing. They requested R642 for the belt to be changed as the current one was already deteriorating. I paid the amount with a heavy hart. Not even 2 weeks later, my alternator belt FELL OFF while I was driving on the highway I might add. I insisted they come out to my house the following day to fix their mistake with no fee attached to this service. The Manager gave me attitude saying they first have to find the problem before discussing prices. They came back to me saying the alternator pulley isn't the right one for my car and that they don't check it with a routine major service. They requested ANOTHER R690 to replace the pulley and the belt. As if I'll go back to them to ***** something else up. I urge you to do a thorough check of the place you're getting your car serviced before booking it.
