I have received too many calls to remember from these people. They ask for the person in charge of the ATT. I have requested multiple times to quit calling me and I have even left a message on their machine to remove my number. I received another call today and ended up having a very heated back-and-forth with a guy who stated I had never asked "him" to remove my number. These people are scum and I hope karma will slap them without mercy.
Call 1-888-772-4724, its the Birch Communications customer support, press 4 to speak with a customer support person. I run a business and its disrupting my store. The man I talked to seemed nice and didn't know what was calling me, but he said he will try to get me off a call list if its on their system.
Also the number that continues to call is also 302-319-5125 and an automated voice service, with no one manning the lines for the customer service for that number.
Guys, these people are not AT&T, they are third party scammers trying to switch you to overpriced third party reseller service. Notice how they never specifically say they are with AT&T. Because they're not! They are ripoff.
