    I really love how this bank believes that a charge on my account is legit, saying I ordered multiple cat orders, charge is from PayPal from China for 53.03, but I have no cat items that they say I purchased everything I have in my house is from yrs ago. The charge is bogus, it seems they stand by the opposite party. I have banked through this bank for awhile. I honestly don't trust them anymore. This happened way back in April and yet I still have no cat items the merchant says I ordered, but yet they get to get the money. It saddens me to see that . I have learned not to trust this bank anymore.
