DO BETTER WE BUY CARS

After a very efficient sales process, I find myself apalled by the after sales service. I purchased a vehicle in November and by December, the engine light went on. We alerted the dealership and were advised to take the vehicle to a mechanic. We sent along the fault report and this is where the slacking begins. Multiple messages and calls later, we are not at the end of January being told we need to claim from a warranty that I paid a substantial amount for, when in fact a part was removed from the vehicle and is not broken. Now when asking to escalate, we are asked to follow another process. And that for what? Another 2 month of running around? DO BETTER
