I cant submit a complaint as it keeps saying seller name incorrect

[padi*0409]

Maybe the seller is NARU (Not a Registered User).

Is it some one you've bought from ?

What is the problem with them ?

Have you checked if they have by any chance changed their username since you bought from them?

Please clarify what you mean by "submitting a complaint".

Are you trying to message them, or are you trying to open a dispute?

Sounds like possibly they are no longer registered.

More info is needed.
