Dropped our truck off to find out why the air conditioner wasn't working. They called and told us it just needed charging. When asked what the cost would be, we were quoted $350. I felt that was too much but my husband said to go ahead. When he went to pick up the vehicle the actual bill was $677! When asked why it was such a price difference, we were told there were extra charges. When a bill is double what you quote, I feel the right thing to do would be sure the customer wants to pay that to get it done! We have been great supporters of Mainline, all three of our vehicle are from Mainline, when our son needed a vehicle we took him to Mainline, we also bought a trailer from there. We will NOT be back!!
