This  number keep showing up. I am unable to return call nor does the person answer .

Called and held the phone. Would not answer.

called back said mailbox full

ADSPLUS displays on the caller ID. Auto-dialed pre-recorded robocall selling some uncertain thing having to do with Senior Medical Advisory and a Senior Benefits Calling List; undoubtedly a scam or insurance or insurance lead generating (i.e., a scam by any name). Our Public Service Commission is shutting these scammers down as fast as they can. Do your part and report; especially if you have any actionable information which can be used to identify the true actors so the State can take action and/or I can use to initiate a private civil action.

Thanks for the information.
