Suspected ***** from FNB

I was making a payment online but FNB was giving me difficulties to pay for my online purchase saying that they suspect ***** but i usually make anonline purchase to that online store. Now it took my money of R1069. It says the payment was reversed but the money is not reflecting on my balance. It is not the first time I takes my money. Sometime this year I made a transfer mistakenly of R500 to my credit card that was closed the R500 never bounced back to my account. This gives me the idea that this bank wants to exploit me as a customer.
