It appears that this is an agency that debt collectors use to outsource making initial contacts for collections purposes. Since the line number (last four digits) shows up "cleanly" (2500), it's possible it's spoofed to hide any number of extensions behind it.

The person that called from this number claimed to be with UPS updating credit card info and wanted my new card number.  As she sounded odd and told me that if I were to do it online it would take 2 to 3 weeks to process I did not oblige.  Be wary

just got a call from915 225 2500,claiming to be UPS and my acct was overdue by $7.50 and she had old visa I no longer had and I told her to run it,Damn Lazy Scammers

Just received a phone call from (915) 225-2500 - the woman sounded very sketchy, so I was wary from the start. She said she was with UPS and that I had an overdue amount of $121 on my account (which I haven't used for years) because the "card on file" failed to process (I never had a card on file). She did have my correct address, but the last 4 digits of the card were random and so were the names and locations of the sender/receiver. Complete scam... And not even a well-executed one. I told her off, then hung up the phone. Needless to say, I haven't received another call.

I just received a phone call from this number 915-225-2500 today Sunday, September 1, 2013, but when I pick it up. they suddenly hang out.  By searching for this number, I found out it belong to a collection agency. Do not know them neither why they are calling me. don't want to receive any call from them.
