Dear Pall,
We have already written to you twice about our a/c for EUR 100,000, rendered last month, and have received no reply. We are unable to wait any longer and, if we do not receive your cheque in full settlement on or before the end of the month, we shall have no alternative but place the whole affair in the hands of our attorney.
We are loathe to do this but, as you do not reply to our letters, no other course is open to us.
