Called AT&T today to block three-way calling, call-return, *69, etc. The charges for those are $1.99 per call etc. I also told them that they say they are providing these features by default for convenience, but is it for consumer-convenience or for profits ? Also it is not possible to unsuscribe from these by logging onto my Internet AT&T account, and one has to wait on phone for a LONG time to unsubscribe.
I have requested the AT&T person I had called up , to make a note of this , to their management.
