theft maybe the word i am not sure but false advertising is defiantly correct

I signed up for the 1200 mbps plan and am at best receiving 600 usually less but with spikes all throughout i have seen it go as high as 900 but this is rare and not constant. I have had 3 different modems in the last 3 or so months due to them having issues. i have recently been presented with opportunities that require me to have at least decent internet access however my service will not hold up to the requirements so i had a technician come out and he was wonderful a very very good tech he covered all of his basses and tried his very best and even made some requests for line techs to come out. I want to make it very clear that i have no issues with his ability as a tech. But was informed that unfortunately there will probably not be any sort of fix for this issue as xfinity likes to keep things a cheap as possible because of the area that i live in not producing enough revenue so this will most likely translate to outdated lines and things of that nature. So my main question is if they know this as a company why would they even offer speeds that they know the infrastructure can not meet? I would assume it is done to miss lead customers into paying for something that they will never receive and unfortunately many will probably never know because they do not realise it. Lets face it most customers are only streaming tv and using basic internet need that only require mid levels of service and do not have the technical skill to investigate speeds and notice that they are being taken advantage of. So they are paying for a premium plan and thinking that is what they are getting just because they never have trouble streaming netflix. In my opinion this should be seen as a form of fraud at the very least if not theft. In this day and age taking advantage of the consumer seems to be the name of the game and that is just a part of our lives now and not much will change because for the most part its a take what you can get or do without society that we live in and things can always be worse but i am approaching this with much patience as i have been knowing that i was not receiving the service that i am paying for but hey it was getting me by but now it is presenting issues that are preventing me from making financial gains and i will have the issue resolved one way or another as i am a very patient but determined person i will be scheduling a tech to come out once a week and i will be swapping out my equipment once a week until the issue is resolved eventually i will peruse other actions i would like xfinity to understand that this is the first time i have had so many issues with a service that i have reached out in this way i am not a keyboard warrior i am not a complainer but the things that i have discovered about this company and its service have compelled me to reach out. It is sad to say that i will ultimately have to break a lease that i just signed resulting in the loss of roughly 2,000 dollars not including the cost and hassle of moving and starting the leasing process over again i will have to ultimately do this to mitigate the loss of funds that i am currently experiencing in the online business world, as xfinity is the only option for my current location. Dealing with this issues and settling is not an option i can only imagine how the neglect of xfinitys infrastructure has limited others. I do hope that we can come to a mutual understanding that what is occurring is wrong on many levels all though this message will most likely fall on def ears. 

Best wishes. Get use to dealing with me
