no message

I have now received 3 or 4 calls from this number.  No message left.  I tried to call it back- says mailbox is full.

Just received such a call.  Pre-recorded message which said to press one to get a better rate on my account.  No company name, phone id says "out of area."  I pressed 1 to talk to my "account manager," when I asked what account with which company this was, the man hung up on me.

I'm pretty tired of getting calls from these people.  They usually call on weekends, several times a month.
