B&B Truck Service dont tell the truth ardmore Oklahoma

My truck broke down in davis okalhoma with no oil pressure, i had it towed to B&B shop, but  tey was closing for the weekend. Monday i called and was told they were checking the problem out and would call me. later they called and told me the oil pump was bad, i authorized the repairs. The follow day i was told that they removed the oil pan and check out #5 rod bearing and it was good and there was no metal in the pan. they called and gave me the total of $1980, which i paid over  the phone, i picked the truck up late and left. Two days later i was greaseing the underside and notice the pan bolts still had grease and dirt on them, and the head of the bolts had no marks on them, I called B&B and was told by WalterBatterton the owner of B&B that he personal took the pan off hiself and left it off all night. I am a mechanic myself by trade and know you cant take bolts out without leaving marks on them and put grease back on them, Alot of companies take advantage of out of town truck drivers , This is One
