Our company’s Adsense account got blocked for no apparent reason, with no communication as to why for over a month - total radio silence. We eventually gave up and just created a new account.
The way I see it, any company that sells a service for money should be legally required to respond to their clients, and there should be an ombudsman to handle any complaints.
Nobody should have to resort to posting an ad in a paper to get support for a paid service.
