Begining July 20, 2021 - August 15-2021 I have attempted to be added as authorized signatory on a family members account. Without following rules governing banking institutions, on July 20, 2021, I visted the bank with my family and at that time he gave verbal authoriation. I then asked for any forms, signature cards or the procedure to be added. I was told that she didnt have any and nothing existed. My family member and I questioned how a saving account was made a Money Market account that has less that 10K. We were told the person who changed the account was on maternity leave and they didnt have any information. Moreover, if it was a money market account, with a balance of less that 10K why was it accuring interest and not being charged fees. The family without me has yet to receive an explanation. I followed all procedures, and jumped through the hoops prescribed albeit most were arbitrary and incorrectly interpreted to be included. I e-verified, my family member gave the account representative permission four times by the primary account holder, and I visted the bank with the account holder. Every step they created an arbitrary response for not adding me. On July 26, 2021, I sent email asking questions regarding the Money Market account, the fact that my family is not and has not receiving any statements, and all related transactions. Although on July 20, 2021, during our meeting, my family member told the clerk Ms. Burchfield to provide me with the information, she did not. The account holder was contacted by Ms. Burchfield who advised him that i needed to travel from CA to OK, to be added. The account holder was upset, and insisted they add me. They did not. Although they called him, they claimed that they could not verify him. It is my intent to hold BOK, accountable for any misdealings or discrepancies that may have occured with this account. They are acting above and beyond their legal authority and providing me with arbitrary guidance, on how to handle family financial matters. I have been denied the opportunity to ensure financial stability and quickly make adjustments in the event of any discrepancies. We recently discovered a withdrawal of 10K, of which we don't have any supporting documents and although requested and I agreed to pay for statements, they have denied me and my family member correspondence.
