Preston Mazda Unethical reston Mazda Youngstown Ohio

Preston of Boardman Ohio sold me a 2009 Nissan Versa SL hatchback with only 22900 miles with 3 bad tires and 1 new tire and broken bumper parts. Tried my best to have problem rectified without success. Asked to purchase tires from them for cost and for them to at least mount and balance for free. The answer to both was no. Gave me the run around on the broken bumper parts also. had to purchase tires from (((competitor's name redacted))) at a great price and asked for reimbursement, of course you no the answer. Felt the car swaying before discovering the tire problem. Have video along with recorded phone conversations as proof. I am asking for help from anyone on how I can use this evidence to warn others. This dealership puts you on a shelf after the sale.
