Express Oil Change complaint: Rat

This tech named Manny didn’t think anyone would call his bluff anyways he charged $113 for a regular oil change with oil filter I had already purchased a Groupon paying for all of what he wanted to charge me mind you I have a four cylinder not a big rig lol my Groupon was for $35 he falsified paper work and made it to $79.99 he also called cops when I told him he was an idiot if I was going to let my handicapped son pay that on top of $35 so total for basic oil change was $148 haha so when cops left he was haggling with my kid saying ok I can do $55 then $30 finally $3.08 so kid paid the $3.08 and this animal helped himself to have him send him 25 through zelle as a deal to let him use Groupon haha kid said no guy got personal info and sent it to himself! Anyways everything was documented and reversed but this POS shouldn’t be working there if he’s doing under handed things! Jerk!
