these people have called 25 times in the past 2 days saying i owe money for a debt i have never had and they were very rude

This number shows up on my caller ID memory 10-12 times every day but they never leave a message on my answering machine. The first call is around 8am and the last call is around 9pm, every single day.  I tried to call back to see what they want but the phone just rings forever with nobody picking up. Someone here said they are a collection agency.  Well, I am debt free (except for a $600 purchase I made a few weeks ago on my master card) and all my regular expenses are paid current, so they need to stop calling my number.

These people have been calling my house 2 times a day.  They never leave a message, and I wanted to check out the number before I called the number back.  The above messages say they are a collection agency, but all of my debts are current.  I wish they would stop calling my home.

I get several daily calls from this number. When I answer, its a recorded message saying call them back, but I didn't call back because I was afraid it was some scam that I would call them and owe an astronomical phone charge or something (I've heard of scams like that).

This number called my cell phone 4 times already since 7:30am today -- this is the 4th of July, a holiday!  When I answered there was nobody there just silence.  So I called the number back and it rings without being answered.  What is this?  I read here that it's a collection company but I don't owe anything to anybody.  Other than my rent that I put the check in the landlord's hand on the 29th of every month because he lives right downstairs.  And the electric, internet, phone & cell phone that I pay by automatic debit from my checking account on the 16th of every month, so no way is any payment ever late.  I don't have credit cards and I never borrowed any money from anybody. If I can't pay cash or use my debit card I just don't buy it.  So they obviously got the wrong number but they won't quit.  That damn number is calling my cell phone again right now!
