Received an automated and distorted voicemail from this number stating that my "mastercard was blocked. to reactivate it, please press 1 now and you will be transferred to our security department." Obviously a scam.

I received the "same" phone call you described, from this number..  210-377-2015 -  They said my Mastercard was blocked and they were transferring me to the security department. Problem is.. they called at 1:00 in the morning; I could not get back to sleep; I don't know how I'm going to function today.  Internet says Ronald Penta, CPA.  Are there not laws against this? Can we make a complaint somewhere?
