I listened to just enough of the message to glean that it was a prerecorded message - consumer alert for people who have taken Xarelto. Then promptly hung up.

XERLETO OR PREDAXA DRUG, "INTERNAL OR RECTAL BLEEDING" "SUBSTANTIAL COMPENSATION".  Last time I checked, usually class action lawsuits are directly targeted.  Not randomly targeted using a robo call system.  I recently blocked this number, and unblocked it to block another.  Now all the sudden they call again.

They are also using skype call.  I told them I was Bill Smith.  They transfered me, and asked me if I was henry, then asked me if I was harry.  I am neither.  Obvious boiler room rat scammer [***].

Same thing here. They call and don't leave a message, and I will be blocking them. Thanks for the info!

I've answered these calls, but they never say anything, and the call eventually disconnects.

Indeed, it's not the drug manufacturer's fault their drugs are rushed to market before they're fully tested.  If it weren't for the lawyers, all those Thalidomide babies would have been just fine...
