> is it not fair to question why this business pays no electricity or either owns/rent the property?
It's fair to question, and it is addressed in the article. They're a subsidiary, and the utilities and rent are in the parent company's name. Other relevant documents are in this company's name, but have a PO Box address because their street address does not have a mail service.
> There's plenty of banks that have to service you by law, go to them, and pay the far higher costs.
I think the "we don't want to service you" angle can be addressed by using alternative bank. However, "we've restricted all your abilities to contact us" is an unreasonable step, and prevents actually refunding the former customer the money they're owed. So that latter action is still an unreasonable step on Wise's part.
