No Internet

Every time we have a power outage and power comes back, I have no Internet. A call must be logged for a technician to switch the box on again. According to technicians a switch trips but it the service does not switch over to a battery because the batteries are to old. Now again no Internet for days. I logged a call on Friday night and still no response. We pay for 50 GB but have no service to be able to use it. Perhaps I must switch to a new Service Provider and cancel this service? Unacceptable!
