50 If an enquiry as to the amount of stamp duty to be endorsed on an instrument arose (generally as a result of a difference between the amount calculated by an Aid & Abet employee compared with the amount listed on the instruction sheet or the attached cheque made payable to the SRO), it was necessary to seek clarification of the discrepancy from the client (including Goldstein Partners). Aid & Abet employees were under direction from Mr Bulzomi that they were to prepare a draft fax about the mismatch for approval by himself or, in his absence, Spiros Kalotihos. Mr Bulzomi approved most of those faxes. The rest were approved by Spiros Kalotihos. After the faxes were approved, they were sent to the client (including Goldstein Partners). Any mismatch in relation to Goldstein instruments was first discussed with Mr Bulzomi, or in his absence, Spiros Kalotihos, before a fax was prepared and approved by him for sending to the client. The client, including Goldstein Partners, would respond to the enquiry by speaking with the Aid & Abet employee responsible or with Mr Bulzomi when the Aid & Abet employee could not resolve the mismatch with the client.
