Walmart Pictureme / customer service

i wish to complain about the customer service i received at the norwalk portrait place.i made a appointment to get my granddaughter pictures done on friday theaug22. someone called and said the computer was down and i needed to change it to sat at 3pm. which i said ok but if the computer is still down please call me back early sat or friday night so i could take her to sandusky and thet said they would. no one did so i thought it was fixed so i take her there on sat at 3pm not only was it not fixed the girl sais i didnt have a appointment. needless to say i was angry and very disappointed because i now did not have time to go to sandusky . we did not get any pictures done . she was visiting from out of state and had to leave on sunday.i look foward to getting a picture of her. i dont know when or if i will take her back there again .and i think this was very poor service
