Alpine Roofing

Alpine installed my roof 6 years ago. During the wind storm the shingles flew off leaving half of my roof exposed. When I called the line was busy for 2 days, then someone kept answering and hanging up or leaving the phone off the hook but not saying anything, and then finally I got through to one of their cell phones (as I had it from before). They informed me that someone was going to come on Friday but no-one showed up, then Saturday, then Monday, then Tuesday but still no-one showed up. They then told me that they could not come for 2 weeks. Meanwhile the rain was pouring into my house. If they had been honest - I would have gotten another company to do the repair. They have also told me the warranty that I have does not actually cover anything and they will not honour it - despite the fact that is says it will cover winds up to 110K and the winds were only 100k.
They do not stand behind their work.
