Mavis Discount Tire review: tires / oil spilling all over my engine

Dear Complaint Department
I spoke with the manager explained my situation and which two tires needed changing first, one that was losing air every day because of a leak in the air entry tube and i had to fill eight pound of air every morning, and the other one that had a nail in it.
I went to this mavis location to get two tires, just two tires new one
ieverything i thought was fine, until the next day at work
my engine was running very strange and the engine oil light came on in my car.
i pulled over open my hood and found my oil cap in the wiper bay and a tool there from the mavis shop, my top of my engine was covered in oil from the open oil portal with no cap on it. I was very upset, i was only getting tow tires, what were they in my oil cap, i didnt autorized any work there, only two tires.
so here the results from my visit, oil all over my car, stop on the side of the road
had to be tow to a AAA service station for 115 dollars, and the cleaning of my engine bay 30.00 and the oil change needed 23.00. so i now stuck with a bill for 168.00 dollar bill for getting two tires at MAVIS TIRES, my solution os to pick another MAVIS tires shop to get the other two tires needed, and for you to honor my price of 220.00 for two tires, less my credit of 168.00 leaving me 52.00 for the balance so i can get two more of the same tires, I do not want to go to orginal tire store, there is one in concord NC, please email me back at [protected]@gmail.com
so I still go every morning to fill up the tire that was losing air, they took the wrong tire which i told the manager i needed gone, horrible customer service.
