Vacuum rage at a Kendall convenience store.

Apparently a guy got mad when the car vac at the store on SW 117 Avenue near the 6700 block ate his quarters.

Miami-Dade cops say when the vacuum wouldn't work, he wanted a refund.

After she told him he'd have to call the company that operates the vacuum, he went outside...tied a rope from his truck to the vacuum...and drove off.

Surveillance video caught the whole thing - and cops would like to have a talk with him.
