ESBI review: Scam

We are also victims of this scam. I read my current Verizon phone bill and noticed a separate charge from ESBI. I called the toll-free number listed on my bill and the customer service rep, named Carol, told me that I had infact ordered this voicemail service when infact, I have NEVER heard of ESBI. She told me they will remove the charge and "BLOCK" my number. They better or all ***'s gonna break loose! The customer service representative told me she was in Minnesota but the billing was in Texas, what's up with that? Actually it sounded like a "boiler room operation" in India rather than a legitimate business.
