Crest Ford

I have a 2015 Ford Focus that's about six months old when I brought it in for oil change/checkup. In my e-mail, I was told the winter check up had a discount although when I was at the shop, no one said anything about me paying. When I left, I was wondering if that meant they would automatically add it to my car's monthly bill. If that is the case (and it does seem that my bill is more expensive than usual this month), then I am upset that someone did not at least tell me this. I should have brought this concern up with the workers, but I didn't think about it until after as I had to leave as soon as I could because of a doctor's appointment that day. I had also been told, when I bought this, that I had two years of free oil changes, but then they told me at the shop that that was not true. I do not appreciate the inconsistency, although I will say that the workers were polite.
