Not a happy customer,poor customer service

We had switched over our service plan and warranty to motor vaps in February as we thought it made better sense having them under one company.In August my engine light came on and we found out that my timing chain needed to be changed,upon opening the cover,the mechanic discovered that a piece of the tensioner had chipped off and the vvt gear had broke off..They put in a claim for our warranty with motor vaps.The warranty asked for photos which where sent by the mechanic and a few days later an accessor was sent.the accessor noted that the car had an aftermarket dumpvavle and the claim was rejected.We where told by the mechanic that the car doesnt have an aftermarket dumpvalve and motor vaps was told of this but the claim was still not honoured. We called to ask what was the problem only to be told that our warranty was cancelled and our monthly fee wasnt refunded and we also noticed that they had also cancelled our service plan and also that money wasnt refunded. Even if we had an aftermarket dumpvavle on the car it's not the cause of the problem we encountered..
