I got a call on my business phone; there was no message.  I star-69'ed it and got the phone number but declined to call until I found out who it was.  Now I'm glad I didn't call.

When I called back, the person went through a 20psecond spiel in about 8 seconds so I didn't understand a word her said.  When I asked him to repeat himself, he was rude and hung up.

I got a call on call ID and call it back, the phone recording came on line to wait, an agent will be with me. I later found it is a telemarketer.

Called our law firm in Seattle, WA informing us that our business could be listed in top search engines such as Google, etc.

called a business with a recorded sales pitch.  They did not offer an option to have our number removed.  I called back and it told me I would have to hold.

rang my cell phone, i answered, a few seconds of silence, they hung up.

this is a business and I waited on hold for 10 minutes to ask to be taken off the call list. The guy said "whatever" and hung up. I called back asked for a manager and employee number and was told they did not have one. I than asked his name and he said Joe but thats not the name he used when he an picked up the line. In short just a bunch or rude people
