Paid for an oil change but the shop didn't do the work
Shops sometimes skip changing filters or neglect routine service entirely while still charging vehicle owners. This leaves drivers with low oil pressure, strange engine noises, and check engine lights despite paying for regular maintenance.

In their words
Unedited, most upvoted first, each linked to the thread it came from.
“This jeep came into the shop yesterday. Had a check engine light, low oil presure and was making some noise. Customer said they have been taking it to another shop up the street to get oil changes every 3 to 5 thousand miles and there was a sticker that said this oil change had 1000 miles on it.”source ↗
“mechanic said i needed new pads so i went and bought some to put on, checked the pads before removing them and they were practically brand new still.”source ↗
“Well, customer did say they only get the oil change. Filter not included.”source ↗
“I was expecting the fluid to be lighter in color. Does this fluid look reasonable?”source ↗
“I have my doubts. I believe they were supposed to do a full brake system flush (at least that's what I asked for). The main reason I have doubts is because the fluid looks virtually identical to how it looked before the flush.”source ↗
“Something that made me a little suspicious was the technician saying "brake fluid always looks dark in Honda Accords." My immediate thought was that maybe he didn't even change the fluid.”source ↗
“That was not flushed. Maybe topped off.”source ↗
“I'm an idiot and got scammed into a different service I truly didn't need (some bogus fuel treatment something or other).”source ↗
“The fact that the bill dropped by more than $2,000 simply because I challenged it makes me wonder whether the original estimate was accurate. I’m trying to determine if I’m being overcharged or if these costs are legitimate.”source ↗
“Now, about two weeks later, I’ve received a bill for roughly $2,300–$2,500, which is significantly higher than what I was originally told.”source ↗
