Blue Ridge Auto Sales My trunk is leaking and they promised to fix!! Vinton Virginia

I bought a car from Blue Ridge Auto Sales, a 2013 Nissan Sentra. I did buy it "As Is" but the mechanic there was a friend of the families and was told to bring the car back with any issues at the time of purchase. Within the first week, I noticed the vehicle was leaking in the back seat and the truck and there was a rubber molding missing from the roof. I took my vehicle back several times and was told they would order the part. On the third trip to Blue Ridge Auto Sales, I was told to just order it from the junkyard and they would pay for it. I ordered the part it was about $50 so I didn't make a big deal about it until the next few days I noticed my trunk was leaking still. I went to Blue Ridge Auto Sales on Friday 9/14/18 and they did not see the leak but told me to put a towel down and come back when we could see where the leak was.

I was reimbursed for the $50 part but I stilI have a leaking trunk. I go back today with a soaking wet towel and no one is there that can help me. One of the gentlemen told me he would make an appointment and let me know when it would be repaired. I didn't hear anything back so I called the Martin Abdul Sales Manager, that I bought the vehicle from and has known of this issue from day one. He told me that he would not help me anymore and that I just kept coming down there to get stuff. He told me not to call him again and hung up on me. I do not want anything but for my vehicle to be fixed as promised from this company. Desired Resolution: Repair Desired Outcome 

I want my truck to be repaired so it no longer leaks. This is what I have been promised since day one and I feel this company needs to be investigated.
