Get a second opinion. Take your vehicle to a reputable tire store and have them check all 4 tires and wheels for damage, tire problems, and/or imbalance.
Are the rims bent? Did you see them while the car was on the lift?

We are close to you.Bring the car in and we can check alignment and balance.Possible even a VSC problem.
