Just Fyi in your case, Windstream actually owns Paetec Comm. I used them for my business phones and internet when I was in Chicago. Not sure why they would have made calls like that. Anywho, just sharing.
I looked up 786-345-1587 on line and it said it belongs to PAETEC COMMUNICATION, INC. but the person answering said it was the WINDSTREAM COMPANY. I told this person about the harrassing phone calls everyone is getting and she told me the Windstream is a phone company whose business is to sell phone numbers for businesses. She advised me that whoever calls, I should tell them to put me on the no-call list, and if they call again, to call the police. Evidently if you use the Internet to put your name on the no-call list, they sell the list to other companies. Basically, Windstream sold the number to a business (probably a telemarketer) and they can dial 20 calls at one time. I guess for privacy issues, she would not give me the person or business to whom it was sold.
Ditto Calabash...I am convinced that Tracfone sells our phone numbers so that the "timesuckers" can attempt to use up our purchased minutes...as always, do not answer an unfamiliar number (you will be setting yourself up for more mystery callers)...this site will tell you all you need to know about the long distance mystery folk and you can escape being the next telemarketer's prey....I do not give my cell phone number out randomly, so any incoming calls I am going to answer already have an identifying name...I block the rest! I have very few spam calls as a result...
