Hey so recently I went to the mechanic and I did have a sputtering problem with my car, and I filled out a sheet explaining the problem I did sign a sheet saying they could do work on it but i never agreed to do an oil change, can they charge me for that?
Did the shop fix your problem? Did someone from the shop explain why they did an oil change? If it’s part of the diagnostic and/or repair for the problem you reported then yes, they can charge you for it since you authorized the work.
