Big O Tires

Be careful! Do not use this big o tires store on geary and cook street.in s. F. For any services.
But if you do use them, make sure you stay there and watch them to do the work. I have been a loyal customer to this store for almost 18 years. It was a great store in the past, but it became a "do not trust" store now. I had some bad experiences with them on my last 2 services, I suspected they did not performed all the paid services. So when I took my car in today for the alignment, tires balance/ rotation and oil change, I decided to stay at the back waiting room and watch them performing the work to my car. First, a tech changed the motor oil. Then my car just sat in the station for 30 minutes, then they moved my car to another station. About 20 mins later, a tech lifted up my car. As soon as my car up in the air on the lift, a service tech called me on my cell phone and told me that my car was ready for pick up. I couldn't believe the alignment had already done that quick, just up and down magic. And I didn't see them re-balance and rotate the tires.
Because they didn't know I was in the back room watching, so I walked out to the counter and acted normal. He wanted me to pay, and told me the services were done, my car was parked in the drive way. So, I confronted him, but he told me they did all the works. Then I asked for the manger, he simply told me he is the manager. (Mauricio c.)
Of course we had some discussion #$@#$*! Then he told me there was a problem, that's why the services weren't completed. I asked him why he lied to me. He answered "I don't want to argue with you". Then he told me the tire rotation was a free service, and he could have someone to do it for me now. That got me hyper! What about the alignment work, I paid $ 400+ for 5 yrs wheel alignment plan. I paid $80 for the tire balance/rotation plan; and I pay for each oil change. There are no free services. He walked away, and came back. He asked me "yes or no if you want the tire rotation" my lord, what kind customer service is that?

Some background info.
I replaced 4 new tires to my car last year, the former manager johnny helped me. I paid $600 for the tires, and paid addition $20 extra for each tire for balance and rotation plan. Johnny charged me another $100 for 4- wheel alignment, because he said it was off. But they only adjusted the front wheels, not to the rears. They told me that toyota did not recommend to adjust the rear wheels.
Months later, I went in for oil change and tire rotations. Johnny helped me again, he told me that my car needed a alignment service, really? I told him that my car had a wheel alignment adjusted few months ago. He told me a car needs a alignment service every [protected] miles. Really? I refused to buy the service, and I told him that they could not perform 4-wheel alignment to my car, so it is useless. Then johnny told me if I didn't do the alignment service, there was no way they could perform the tire rotation and balance service again, he had to void my tires warranty. Then he offered me a discount for a "5 years 2-wheel alignment" for only $399.
In order to continue have the tires warranty, so I did purchase the 5 years plan.
