Internet speed degraded far below original

So i'm getting close to my wits end on this - I have gigablast, and i got ~950 Mbps when i first moved in, everything was fantastic. 

Now about 2 months after setting up my service, my speeds went down and i started having connection dropouts. okay, i'll reset my router and it will come back, but speeds aren't exceeding 500 Mbps now. 

I had a technician come out after 3 attempts to resolve this and it was found that the line into my apartment is okay, but from the building out to the next hub there was some echo in the line. Not something that this guy or myself would be able to fix. He said that he put in a service request to have them look into the line, but nothing came out of it from my knowledge. 

It's now been 6 months since this started and im now only getting between 0.2Mbps and 198Mbps - the problem is getting worse. On now my 4th attempt to ask for someone to look into this, there was a service scheduled to look into the lines outside my building, but nothing changed since the 28th when they were scheduled to come out.  

I'm getting to the point where I am ready to start asking for bill credits. I'm paying a lot for service that isn't accessible, and i don't even have a choice in what provider i use. 

This is a desperate cry for help. i just want my gigabit speeds. 

I've attached some of the connection data from my modem which hopefully can provide some information for those who are able to read it.
