Claimed they were calling from AT&T and then continued on to say that they will lower my phone bill, etc. They tried to rush me into answering yes / no questions that agreed to use them as a provider, then I heard "Birch Communications". Definitely not AT&T, eh?
Said they were calling from AT&T to correct a previous billing charge and we would be credited next month but needed to transfer me to supervisor to confirm I had been told about the credit. Then tried to trick me into confirming I had been told and "accept" the credit. At this point said they were Birch/Byrge Communications. I could tell that they were trying to trick me to say yes and accept whatever it was they were trying to sell.
