Unfortunately I can't give zero stars, hence one star. I have never been their customer. I rented a house where previous tenant had been using the Bulb. And I am now harassed for some unsettled bill. And I can understand it. But the customer service is nonexistent. Nobody answers the phone, nobody replies to a number of my emails. I managed to have a on-line chat and explain the problem only to get another bill. Now I am threatened to be referred to debt collectors! Stay away from the Bulb, they are unfriendly and unapproachable. The irony is that I have never been their customer yet have to deal with them.
