Business ProfileforSakelaris Buick GMC of Lebanon

I took my GMC Acadia Denali in to the service department for a diagnosis on 3/22/24. I asked the service manager ****** specifically ( multiple times) to have the tech drive the vehicle. I explained what it was doing and told her that the tech would have to drive it as there were no engine lights on. They scanned the vehicle but did not drive it. They swore all my issues were caused by a fuel pump. I agreed to have the repair done and scheduled it for 3/26/24. Upon arriving for the appointment I once again ask for it to be driven before any parts were thrown at it. ****** told me since it was on empty they could not drive it. ( I was told to bring it in on empty) The fuel pump was put in, once again I requested they drive it. ****** stated she drove it and there were no issues. Upon driving the vehicle home I noticed the vehicle was doing the exact same thing, but worse. The vehicle was not fixed. I called ****** on 3/27/24 and tried to explain it was not fixed and was actually running worse. ****** got very defensive and stated the computer stated it was the fuel pump and if there were other issues I would have to bring it back for more diagnostic testing and pay for all further testing and repairs. I tried to explain to her that I requested they drive it before any repairs not just after so they new what it was doing. I explained it was still doing the exact samething. She stated they followed protocol and put in the part the scan stated. When I tried to explain that they did not fix my vehicle they actually made it worse she got very defensive and stated again they followed protocol. She did not want to even discuss the fact it was not fixed, she actuly suggested i take it somewhereelse. . Since having it "Fixed" it is running worse than before and has now thrown engine code. I am covered if I return the vehicle they will do further damage to it. I spent all that money and my vehicle is in a worse mechanical state.
