Royal Financial Bank — Charging for COT AND IMF CODE

Hi,

I have come across this incident where in huge amount of money of 72 lakhs I had to transfer from Royal financial bank to my local ICICI Bank in India... While doing so they asked to Pay COT CHARGES of 5, 50000 and then 10 lakhs for IMF code. After the payment I was shared with codes which could processed further and transaction showed successful... Even after 15 days the amount was not transferred.. on following up on whatsapp (+44) number, they saud it's bounced back and redo the transfer.. while trying to do it's asked for COT and IMF codes again for which they are asking again 2.5 lakhs.. what should be done

The internationational bank is royalfinacialbnk.com.. my account was created here to deposit money which I received from custom and paid all custom clearance and certificates charges
