one of many that calls my cell

called and left no message

Called my husbands cell phone 2 days in a row asking for me...when he said that I wasn't there they hung up on him.  He tried calling the number back a few times and it is ALWAYS busy.  Today I was home so I answered his cell and they said "Hello Jennifer this is Publishers Services calling you long distance can you hear me?"  I said yes and the he hung up on me!!  What's up with this company???
