Who is this calling here without leaving a message?

Emergency medical alert systems for those over 65, already paid for by company as well as shipping already paid. Offered a discount pharmacy card, free of charge. Press 1 to verify address, 5 to notify shipment received. Pressed zero to hopefully speak with someone about getting the number removed, ended up with a dial tone instead.

no message left.

We get calls from this number at least every week at the most inopportune time. I have learned to ignore it if I notice the number or if I sometimes just pick up the phone without looking at the number, when I hear the statement "important information for all seniors" I hang up.

Received a call from this number a few minutes ago.  Caller ID said Toll Free caller.  I did not answer, left no message
