CARS Protection Plus Did not pay for repairs that were covered. Murrysville Pennsylvania

I have not had any positive experiance so far with this company. Ive had customer service issues ever since the beginning.Last year. while on vacation 1500 miles from home, I needed my vehicle fixed. Cars agreed to pay for the repair.  On my contract it says if something on the list is broke, I pay $100 deductable to get it fixed. My bill was for over $200! They refused to pay for the whole bill. They also wanted to use a junkyard hub! After arguing and even the garage tried helping, I ended up paying the entire amount myself! I was told I would be getting reimbursed for the small amount they agreed to pay. I never recieved a penny.   

Now I need more repairs,a year later, the parts are on the list,and Cars once again agreed to pay. Suprise, they will only pay for half the bill!  Over 400$ this time. The garage was completely shocked. He said he's never had this problem with other warranty companies. He also said they were very unpleasant to deal with! Very unprofessional. I tried calling Cars, and it was very unpleasant. They told me it was a misunderstanding, and the garage wanted to buy better parts,and they won't cover that. So I asked where do I bring my vehicle to get it fixed for the $100, he said he didnt know. That its up to me, and why should he know. I then talked to the garage about the overpriced parts, he ordered the cheapest ones. Im just hoping these extra cheap parts hold up while I'm towing my RV across the country next month!
