In this company something has changed a lot in recent times.
I passed the initial identity verification and registration a couple of years ago in one day, almost instantly. Utility bill was enough at that time.
Now my address has changed and I decided to make changes to my account. My utility bill doesn't suit them anymore. As if it seems to be illegal (they think so). Although there is a barcode and it can be scanned by QR-scanner (if there would be a desire).
I sent them a certificate from the bank with a seal. That was not enough for them either. They asked︀ for a list of transactions for this bank account. List of bank account transactions! To︁ confirm the change of address, Karl!))
In short, they behave strangely. Although, in general, they︂ had (and maybe for someone even now) a good and convenient service. It was.
