Offline more than they are online

This company is one that I would not even advice my worse enemy to get them as a service provider. They are more offline than online, yet come monthend they want full money from their customers. When you call them ans they hear that you want to log a call, they drop calls on your ear. It's the third day since October started, we are 3 hours online and the rest of the day off, even now we are offline as we speak and have to buy data, yet we have Wi-Fi that we pay for.
