Fairway Chevrolet

Took our truck in for a oil change, 15k service and to have a noise diagnostic as the left front shock/ ball joint was squeaking. We were asked if we had used any of our 2 free oil changes yet and we hadn’t. This was our first service. We were called a couple hours after we left the truck with service and were told we weren’t eligible for a free oil change as they were already used and would have to pay $70 for it. We argued that we haven’t been to any Chevy for any oil change and there had to be a mistake. We did buy the truck with 6k miles on it and the service lady said the first owner may have used them both already. We said that couldn’t be the case as there is no need for 2 oil changes in 6k miles. That 2 oil changes should still be available. We were told we had to pay the $70 oil change still! We feel completely cornered as the oil change was already done at that point and we had no choice but to pay it. On top of that they said they fixed the squeaking by lubing everything up really well but that if the problem persists they wouldn’t cover the cost to fix it again. We were also told it is highly recommended to remove the lifter blocks from the back end, as they are very unsafe even though we bought it from this dealership this way! They said if anything were to happen that it wouldn’t be covered! We are completely disappointed that we bought the truck here with a bumper to bumper warranty only to be told no oil changes are covered and that we are driving an unsafe vehicle that was bought in this condition!
