What does the verification have to take days for verification at first and not even that you are doing a wallet account upgrading? That is the 1st moment of suspect.

OP,  you too would had make your research if such strange wallet site is not only a software program specific for the site in use of scamming people because if the wallet does not permit other usability to other means of transactions then it does not seem trust worthy.

Again,why didn't the guy who offered you the job guide you by himself instead of redirecting you to the customer care? That is basically basis of your billing as a victim and then finally you were asked to pay for an OTP. What would you do that?
If it was a demand that you needed to pay the fee inform or gas to execute your withdraw transaction, that would had been more convince able but yet not still enough to believe it is a legit.

What is the nature of the job and what are the tasks layed on you as an employee there if I may ask? But anyhow, stay away from it because you are closer to be scammed and I also expect other forum members to take note of rus scamming strategy as a noted experience so that you do not have to fall victim otherwise.
