This company - Global - has repeatedly call my telephone number about some outstanding debt with Capital One after being told they have the WRONG person. They have left threatening messages about their final process, which never seem to happen. Another telephone number used is by this company is 208 649-3241.
I have told the callers I have never had an account with Capital One - and - that there is not a person named Glen at my telephone number.

They keep calling my number even  though I have told them they have the wrong number.
I told them to stop calling but they pay no attention.

Suggestion,

If cell, where you can, save no to contacts and set ring tone to "no ring".  Never answer and they will eventually give up.  Most important, never talk to them!  With it set to "no ring" you are never bothered by them.  As you get additional calls from them, add as additional no. - cell, office, home and even fax, ever how many choices your contact system has, then start a new one on them if too many numbers.  
Put a "Z" in front of name so these collection numbers are at the end of your contacts list out of your way.
