(1) Delay in margin withdrawal: I requested withdrawal of 30 million won of margin on March 28th of this year (2024), but {out of about 70 million won of margin ($53,336.65; account 100276)}_only 2 months have passed until May 29th of this year (2024). Even though the head office said that the withdrawal decision had been made, the account has not been deposited yet. (2) Request for additional costs: In response to the request for margin withdrawal, there was a request from GRG head office to transfer two types of additional amounts, a. - Approximately 13 million won. A remittance was made on April 5, 2024 to withdraw the margin in response to the request for "currency exchange cost", but -# the refund of the exchange cost and the accounting of the deposit (margin) have not been implemented even after 2 months. b.- When I objected to the request for 10 million won as “verification funds” (dated April 5, 2024), there was a reply from the head office (May 7, 2024) that the request was “ineffective.” (3) Financial Disadvantages: This investor is notified that he is suffering significant financial disadvantages (approximately 10 financial institutions demand debt every day) due to not receiving margin withdrawals in a timely manner, and exposes the above unfair trading practices. (4) Attachment; Deposit remittance screenshot photo, dealer background screenshot photo, and one type of reply letter from GR Group headquarters.
