If you want them to stop harassing you, call their toll-free number:

1-+1 888-311-1121.

You can get a hold of a real person at that number. That's what my husband and I did, and they finally stopped harassing us.

Also: They have many many complaints made against them at the Better Business Bureau. If phoning them has no effect, you could try that route as well.

it is a collection agency cause they keep cxalling my phone forn my ex

I get wierd calls for my brother, I think collection agencies.

stop calling

This is a collection agency in Vancouver.  To stop these calls simply do the following:  Call the Privacy Officer of CBV Collections.  In Vancouver contact Erin Coe on her direct line (604) 661-7902. Tell her you want your number removed from their system.  She will ask you for the number being called.  Then she'll ask you if you are such and such and whether you live on a certain street.  In my case both were for a company I've never heard of.
She'll then tell you it takes 24 hours for their system to get updated and the calls stop.  Hope this helps you out!
