Make a Formal Complaint Regarding Failed Service

I'd like to make a formal complaint for the Rocky Mountain Region of Colorado for repeated full internet outages in addition to exceptionally low running speeds for the past four months. I started seeking help through the app, then moved on to the call center. After several weeks, I was given a local contact in charge of operations in our area. I was to work directly with him to resolve things. Some service improved for a few weeks although we continued to have very slow speeds between 5-10pm every night. We pay for the highest internet speed to accommodate working from home and children needing internet for school. The slow speeds mean we limit who is on the internet to one person at a time so that necessary work can be done. This is absurd for the 1200 megabytes per second we pay for.

The original two technicians who came to our house explained that the service lines and equipment in our area were outdated and, essentially, the service level was oversold to our neighborhood. They referred to a 'node' that receives the larger lines and then distributes the power to a general area of customers. We were told that our home was the 'last on the line' which meant that our service was affected the most. In the winter, they promised a huge upgrade coming to our neighborhood to improve all of the infrastructure. We were told our area was a priority because of the level of disruption we've had. Since then, an amplifier in our area has gone down which meant new outages, up to a day long. Since its replacement, the service dies every single night. I'm told it is because the network needs to rebalanced and this can take a few days before they know what isn't working. My understanding is that they only know of a problem when a customer complains. It has been 11 days like this. I've been passed on to the next level of management for operations in this rocky mountain region, [Edited: Personal Information]. I was now recently told that the concept of having bad internet service due to our location on a systematic line is outdated. Apparently, this is now how the system is configured. So, either the first set of technicians lied to me or the current people are lying to me. Either way, nothing is being done. All winter they said they were just waiting for the ground to thaw to being work. The ground is plenty soft as I have been doing landscaping for the past three weeks digging into the dirt by hand (nowhere near these lines by the way). 

Comcast has a monopoly in our region. There is literally no other internet service aside from satellite- which is not very reliable in the mountains. We pay the highest fees for service and get the worst results. I am appalled that this is being handled so poorly and that I have been lied to. I've spent many, many hours on the phone, texting and having technicians at my house to find where the problem lies. The only compensation I've received is a $50 rebate and then another month of service rebate. Both of these I've had to request despite the horrible level of service. This is a disgusting way to treat paying customers. I will be starting a local campaign to get a new service line installed in our area for Ting. I literally do not know of a single happy customer with comcast in our area.

Comcast, fix this now.
