Unimpressed - Repeat offender

A few weeks ago my burger bun was burnt to a crisp and the chips were old. Went back last week and the patties on mine and a colleague's wacky Wednesday were raw. One can never get through to them on the phone to place an order and when you visit the branch you see them ignoring the phone even with no customers in front of them keeping them busy. Even if you do by some stroke of luck get through to them and place an order over the phone, you wont find it ready when you go pick up, I have experienced this twice now.The staff is rude to say the least, I am not the only one to have noticed this from my office. They hardly greet and seem to get impatient if you have a large order, or are unsure what to order or most especially if you have a complaint. I work in an office not far from there with just over 120 employees, and we have all vowed not to support this particular branch anymore. Customer service/satisfaction does not seem to be a priority, we cant be supporting people who don't appreciate that we work hard for the money we spend there.
