hello, I finally received the voucher. I wanted to redeem it but Silivano auto repair claims that its only for ONE oil change not three. I cannot contact "Auto care special" because they do not answer the phone or return my calls. I am very disappointed with my first purchase from living social, - absolutely nothing about it went smoothly. As I have not used the coupon, neither do I intend on going through with the aggravation of a second attempt I am requesting a refund. Thank you
