Things that make me go hmm… Medicare Cannot Fix Email Problems Without A Medicare Number

Today I tried to convince Medicare to stop sending me emails that should be going to a different person. I called them on the phone and they were apologetic but they said that they cannot do anything with MyMedicare.gov accounts without the Medicare number. That is a strange way to run a web site. Since I am not interested in hacking into his account and none of his emails has his Medicare number on it, I guess I need to grin and bear it.
