Satellite is not working again

I had a tech out on Friday because we kept getting message 775. After a few hours the tech got it working. The next evening it went right back to message 775. I have done all

the trouble shooting techniques again and it will not work. As I am still paying for service that is not working and ordered a movie Saturday evening that we didn’t get to watch as that is when the service went out again I need to have this fixed and the tech back out today. I have been trying to call since Sunday morning and can not get through to a representative. Please help!!!
