Hello, good morning, Erick, my name is Isai, and I spoke to you on July 27 about my problem that I had with Faissal about the coupon that I provided for a discount for an oil change. I told you what had happened, and you told me to leave my receipt with you along with my name. And myand cell phone number, and that Jonh Gorence, the service supervisor, told me that he was going to call me if I received his call from Jonh, but at no time did he offer me an apology about what happened, and I did not see any adjustment inon my receipt, as you had agreed. I am displeased with the service you givegave me, and I would like to speak with someone who is a superior to you. I'd appreciate it if you could help me with this, thanks.
