I went to DQ last summer twice now and after getting coupons sent to my home, I would try to use it; but when I go there, there smoothie machine never works and weeks later I go back and they still didn't get it to working. I called up Customer Relation right after the second time of going there and they said they emailed me but yet have not found anything on it; then I called again before I go up there being I got another updated coupon and I wanted to see why I didn't get responded to. They made another report for someone to call me but I never got a call to show concern or apology when getting their coupons at this location. That's pretty shame when they're doing business but don't know if they're getting burnt out or losing more help or what? But why they keep sending me coupons if I can't use it closeby?
