they were very rude and said they are suing me and i was a liar and hung up and won't answer my phone call since they hung up on me.

it's a collection agency... here's their link: http://www.assetmax.net/

shows up as "unknown" on caller ID - don't know why the cellphone carriers don't let you block unknown and blocked phone calls (like on land lines)

this number is from a debt collection agency

has this agency stopped bothering you.  started getting calls from them.  not sure why, as i am not delinquent with any of my payments.

I have received many times a message from this number. Any clue what this might be about ?
Best regards,
Andre
