AT&T service problem

We were very disappointed from AT&T's service technician because they supposed to come to the house yesterday to fix our Internet connection since it's been 1 week already we didn't have good service for Internet connection from them so they promised us that they will come Thursday between 8-12 pm but instead they showed up Wednesday at 2 pm and left a note saying "Sorry we miss you". We were not home that time because we were not expecting that they'll show up and we also had to go to work. So yesterday morning I called AT&T costumer service to tell them what they did and letting them know how frustrated we are from their service. Now they give us another schedule and that will be on Tuesday Jan.20 and hopefully they will show that day or else we're gonna have to cancel our contract from them. It is very frustrating when you don't have Internet at home and I know most of us feel the same way. To all my friends, I am not gonna be around for a little while online but for sure next week I'll be back. Have a great day.
