Firestone Complete Auto Care

I purchased a CMS coupon book which included coupons from here for one (1) free oil-change and three (3) half price changes. When I called to make the appointment as specified on the coupon I was told I could only use the Free coupon after having used the half-price ones first. No statement on any of the coupons indicated this was true and I later spoke with another contributor that had similar coupon s and they confirmed this was an inappropriate requirement. Bottom line, if they'll willing to cheat me out of a fund-raiser coupon, what else might they be willing to cheat on.
