Got se several calls from that number at any time of the day.
when I returned the call, a voice recorder came on saying it was CBB agency. I hung up.

Not sure it's a collection agency..I answered it and recorded message of a female voice started rambling off a number "1 billion 9 hundred thousand and something and repeated itself 3 times then the line went dead"

Just call them back, wait on the line and with a firm tone say "By law you have to stop calling me upon request. Please remove <your number> from your call list immediately". They'll ask you if you are someone (for me it was Dina) just say no and they'll remove the number. If they don't, they are breaking the law :)

robocall from a collection agency.  calls begin at 8AM and stop at 8PM monday to friday and are spaced out about an hour apart.  picked up a couple of times and you get an incoherent robotic message and then you get dead air.

ya i got the phone call about 7 times today from that number while i was at work. phoned me on my cell but i didnt answer, at least now i know that it is a collection agency. damn scammers!!!
