Within the last four weeks, that's 31 days, I have had a receiver and modem replaced and once again my "signal has been lost." When I called to report the issue I was informed that a technician could once again visit me between the hours of 4-8 P.M. So, after having no service more than having service this month and after wasting four hours of my evening waiting, no technician arrived. Not even a phone call. Of course, the office is now closed. Customer service at its finest. I am incredibly perplexed that AT&T thinks this is acceptable.
