I am currently at a small standstill with my LOC.  For three of the last four
months, I have been getting many 900 number calls billed to me.  They are
plainly marked as having come from a local hotel's main number.  (The calls
are all to sports lines, so would not be surprised to learn that bookmaking is
taking place.)

I have called the LOC each month and they have just told me to remove the
calls from my total (one fellow DID mention that I should remember to deduct
$nn for the rebated taxes.)  That's fine, but I really would like to
understand how this scam happens.  Is there anything that the list can suggest
to remedy the situation, short of removing my ability (as well as their's) to
place third party calls to my number?

The bogus bill is not over $20/month yet, but it is growing exponentially.
