they are cold calling off of a list they purchased from either a bank or some other finacial institution (credit card, store card etc) the "number not in service" is due to these types of companies having multiple lines on a call center.... the out bound parsed numbers are not set up to be rung back, hence that message. (like when you call an 800 number, you cant usually dial directly to the clerk)
I totally agree. I seem to be getting at least three from new/different number each day. If I do not recognize a number I do not answer. I've been known to answer, but not say anything. Computer activated calls do not transfer to a human unless it hears a voice. Then I know I was not being intentionally called by a person who knows me for a legitimate reason.
Calls my home phone and leaves no msg. I recently have been getting at least 3 to 6 unwanted calls a week. There usually is no one on the line, I think they are verifying the number is good to sell. I am on the do not call list. Doesn't seem to work anymore. Has anyone else noticed an increase in unwanted calls? I use to get maybe 1 a month. The only things that is different is I listed my home for sale on Zillows and my number is the contact number. I expect there might be a program reading through the web gathering phone numbers. For those that don't know, caller id can be set to anything the phone owner wants it to be set too. Especially cell phones, on Verizon all you have to do is log into your account on the web, select the option and put whatever you want people to see. Seems unethical to me, but it can say anything.
