I have been getting calls from this number for several months. It's a recording as indicated by kmann (above). I finally copied the number down and tried calling but got a message to dial "O" which repeated itself about 10 times but never got to speak to anyone.

Someone has been calling my work being very rude to my supervisors stating he needed to serve me papers and she had to be a witness. Left 8556724681 as a call back number i called the number i got a recorded message saying it was cohen kaplan and tulowitz. I have also recieved call on my cell from a darren knight claiming to be from this company. Caller id shows a completely different number. Says i have two claims against me and if i do not call back will go to court and wishes me good luck.

Just so you're aware, this is a collection agency.
