Called and left no message.

These guys have been calling like crazy the past 2 weeks trying to "Assist" in lightening the bank account. Calling from:

331-305-4198
408-508-6339
480-253-9977
682-305-0799
903-686-9303

call started off with a msg from bradley that my business could be eligible for a front page listing on google searches. "press 1 to speak to rep" -- so I pressed 1...spoke to a rep.. acted like an idiot to annoy them. I started to ask for their name and the company's name - then Cheryl hung up on me.

Called me too tell me that my business could be eligible for a front page listing on google searches also. I hung up and called back, and was given the choice to be on the do not call but was told it would take 48 hours to take effect. The then called me again 2 days later to tell me that my business could be eligible for a front page listing on google searches. I registered with the National do not call Registry on Jan 16 2013 (over 2 years ago- but is permanent) and have not operated this business they called me about for over 4 years, thus there has been no changes to phone number or registration. However I did buy a new phone from Verizon but did not change my number just recently. I wonder?
