enough is enough

They have called me for several months. I am fed up with their waking me up at 6 am.

I have asked them to loose my number that I am not interested,
they (US Pharmacy) keeps on calling

Pretty sure this is again US Pharma, using a different but very similar number.  They were using 646-503-1425.  Ridiculous they can't stop these people.

I received a call from this number but they left no message.  Caller ID was unavailable.  I don't answer calls from people that are not identified or if I don't know them. I assume it is someone trying to sell me something or its a scam or both.
