Thanks for posting! I am sorry to hear about your issues with your internet always going down, this must be frustrating so apologies for any bother.
I have tested things from here and I can see that all of your downstream power levels are too high and will require an engineer to attend and investigate things further for you.
I will send you a PM (Purple envelope at the top) detailing what's required to proceed with making the booking. Please respond to me there and I'll get this sorted for you.
