We don't know if the TS was offered an earlier appointment time that he refused, although it doesn't sound like he was. We don't know if the date offered was the first one available. All we know is what he said in his post. What you and Bill Broderick suggest is pure supposition.
you are the one who does not know.
When know for a FACT that the OP was offered the EARLIEST appointment available, is 10 days from whenever he posted, he took it!
"i would like to now why it takes so long to my system moved to new address we are having to wait over a week for direct tv to come install at news address i placed order on 3/14 and have to wait 10 days before they come and install .""
The above indicates that there is no appointment available until 9 days from today (he posted yesterday) making this the FIRST available appointment, there is nothing available BEFORE, but there is sure something available AFTER, which YOU can freely choose. So you can either take the FIRST available or ask for your BEST convenient appointment AFTER the FIRST available appointment. YOU decide, NOT DirecTV . Capisce
