I can say you owe me money too. The hard part is collecting said money. The overheads of collecting from a non-cooperative customer would not make it worthwhile.
But what if they pass it to a debt agency? I think it's a risky strategy.
Ignore it? Even a debt agency has profit margins to hit and wouldn't take on unprofitable clients.
Depends if they allow signup from a prepaid visa.
There's no one to chase, its a prepaid.
