I had the same cancellation issue.I ordered Direct TV thru AT&T.
The representative only told me about AT&T's part. When I called Direct TV they told me about the entire scam. I had 24 hours to change my mine, NO ONE TOLD ME THAT. Direct TV Mailed out some information I received well after the 24 hour period; therefore, I still was out of the 24 hours period.
The Direct TV Rep. said I still could have called on Friday, B.S.
Direct TV would still have said it was not within the 24 hr.period.
DIRECT TV IS A SCAM.
