Just wanted you to know that recently I went to pepboys and an inexperienced employee was to change my oil. Upon completion I was told there was no oil in the car to drain. I checked it a couple weeks later, it was overfilled by 4 quarts! Apparently the bolt he removed was not the drain plug, thus the error, fortunately after changing the oil again the car ran fine.
That is when you should have asked for the manager and had him check your oil level . Also you should never wait more than the next day to check the oil level . You really should have done it before you left the place.
What you need to do now is check all your other fluids
What if the guy drained some other fluid by mistake . . .
