West Asset Mgmt...collection agency.  They have MANY phone numbers and they rotate them.  My husband went to a new dr FIVE years ago and six months later these yahoos started calling about a $200 hospital copay. The dr billed thru a nearby hospital and showed my husband had an ER visit.  Tried to fix this for a year, told them to stop calling, sent them a registered letter and nothing changes.  Now I block the calls and have moved on!

Same here.  I keep missing the calls, but the number only calls my work phone and never leaves a message.  I've tried a reverse phone look-up, but I can't find a listing.
