I was once a victim of this scam before, infcat them wipe away my 20k and the remaining change them.use ammm buy credit, na through that number we later take track them, EFCC been blocked they account then, but still this scam format still exists and I receive calls almost everyday from the acclaimed okay officials.
We all need to be careful out there and try as.much as possible to act in the most security guided ways, never give out any security code sent to your phone.
Scammer no dey ever rest, they never rest, that is, as on strategy dey cast, na so them dey come up with another strategy.
Me I don dey use opay for more than 4 years going to 5 years now, I've never fallen victim to any scam that is related to opay Sha, but I've been scammed before through my zenith and access bank, and even though I report3d this issues respectively to the banks when they happened, the two banks did nothing to help me recover my money back..
Access bank told me to go get a court order to allow them access to withdraw the money from the scammers account and credit it back to my own account, I spent time and money to get the court order, plus other necessary documents, I submitted all the requested documents and every thing was accepted and the bank told me that in the next 3 business days, I would get my money back, it's been over 8 years now and I never got that money back..
This is just to say that scam can happen with any bank, doesn't matter whether it's online banking or physical banking, we all should always be careful at all times.
