How can I get a tech to my house?

Call 800.288.2020 and settle in for a long wait. Lots of people are being inconvenienced by the current situation. Sharply reduced call center staffing, technicians not available to work due to health or family issues, record-setting call volumes and a growing service backlog are causing difficulty in getting through to AT&T (and the other communication companies, judging by social media). You'll have to keep trying and be patient.
