October 13, 2020
Been banking with RCB for 20 years now after today this will probably be my last year I was in a car wreck and my car was a total loss insurance set me a check. When up to the bank to try to catch it so I could go buy the car that I put on hold at the dealership They told me they were unable to cash it for 3 days. Thinking the check was not from a Reputable company. However it was from progressive. progressive is one of the most known widely know insurance company in the US. Even has stated on the check stub. That i tried to show the. So next week i will shopping for a new bank. Kind of sad i have deposited a hundred thousand in the last year between the 4 acct in my name not to mention my husband acct ..sadly if bank manger pam on north 14th in ponca city would of took the time to look at it instead of just say no. Smh time to find a new bank
