Trying to get Direct TV and internet service from at&t

and it has been a total nightmare. Had an appointment from 8-12 thurs. Tech. called and said he was way behind and wouldn't be there until 5pm. Called back later and said wouldn't be able to make it all, but another tech was coming to install. No one ever showed up. So fri. morning went back to at&t store to find out whats going on and they scheduled another appointment for Sat morning 8-12 but said they would try to get someone there that day. About an hour later a tech called and said he would be there in 30 minutes to install. About 30 minutes later he called back and said his boss just took him off the job and sent him to another job because our appointment wasn't until sat morning. Got in touch with the boss that made the change and was told he would look into it and see what he could do and he would call me back. All day and no call back. 10am sat morning called customer service and was told the only appointment they showed was for Thurs. Dec. 13. I said thats impossible i watched the guy make the appointment for sat morning, someone must have changed it without saying anything. I was told I would get a call back from a manager that day (sat) to try to resolve this. I told them to add in the notes that if I didn't get a call back today, I would cancel the order all together and go with another provider. I was assured I would get a call back. All day no call back again. I've never been through anything like this, so much incompetence and bullshite. Has anyone else experienced anything like this level of bullshite with at&t?
