Dun and Badstreet /RemoteFreelance review: Freelance job payment

Hi

my name is Rifat Noor Hussain I am contacting you from the UK. I completed a job for the above company when I took the job they were emailing me using remotefreelance. I was expecting my payment for the job on 26th of September which I completed within the deadline expected. however they wont release the funds.

They stated that I need to pay 250 GB, which I have but know say the payment is lost and I need to pay more money as an authentication code to be verified for your bank to release the funds.

Please I would really appreciate a reply, as I am very worried and upset to the point that my health is being affected.
