I am very frustrated with Tire Discounters corporate office. I have been waiting for a call from someone higher to take my complaint. Ive called multiple times and no one has returned my call. Your in the mix of not taking anymore services for my parents or I. I highly do not recommend Tire Discounters anymore. I have a credit card with them and gave them a lot of my hard working money. There employees messed my car up but they don't want to take responsibility of it.
