Select Home warranty Won't pay for covered services and won't take or return my calls Mahwah New Jersy

I have a broken flap on my refridgerator door that lets the ice cubes out but does not close properly. I called them two weeks ago but now the won't take/return my calls since the next situation. A few days after submitting a claim for the flap I discovered my hot water heater was not working and one of them was leaking.

(we have two 50 gallon hot water heaters) their contracted rep came out and replaced the hot water heater that was leaking (after he called into and select home warranty) and the 2nd hot water heater had a broken control valve which he replaced. They sent me an email saying they don't cover hot water heaters that leak. 

After I sent the claim ticket in to try and at least collect the $315.91 for the bad control valve on the 2nd hot water heater they said it was not pre-approved. I explained that the contractor called in to tell them what he was doing before he did it and now they will not take my calls.

At this point I thought that maybe a leak in a hot water heater was not covered by a typical home warranty but after calling a competitor they said it would be with them.

They have my cell phone in their caller ID so when I call in they do not pick up.
