Sending an email to COX, I would like a resolution.

To whom it may concern, I want to start by saying that I am EXTREMLY DISAPPOINTED with my COX internet service. First, I would like to point out that I have recently moved from a location in Scottsdale, Arizona to Anthem, Arizona. Since my move, I have had nothing but problems with my internet. COX has been my service provider for around the last 15 years, for entertainment, business, and educational needs. There has always been little issues that would come up here or there and then get resolved. However, it seems of the last three years or so I have struggled with my internet connection more and more. It takes time to call, troubleshoot, setup appointment and schedule all of it between more important tasks in my life. Currently I pay for the premium internet service. From what I understood in the last couple of emails that I received about the upgrades it that my internet service was supposed to double. This seemed very exciting and reasonable considering the amount of money I pay for the premium service. The speed was supposed to be up to 100MB down and I figured that there would be a decent increase in upload as well. This actually was working fine before I moved; my service would range from 80 – 100 down on average and 8 – 12 up. This is an acceptable range, of course I am not getting 100 down 100% of the time but 20% decrease during busy hours was acceptable. Since moving to my new home in Anthem, I have had nothing but problems. All my computers, OS’s and equipment are identical but my speed on average has been lower than the next lower tier service. I see latency problems, drops in speed, disconnects, and on average I am getting bellow 50MB down. Why am I paying for a higher tier of service only to get speeds less than the next lower tier? COX technicians have been to my house looking into the problem, they tell me it is my computer or my cable modem. However, I have switched out the cable modem, I have bypassed my router, I have tried different computers and laptops, and still the same intermittent problems. The last COX technical representative was even making changes to my registry on my personal compute when I was not home and my fiancé was there for the appointment. At this point, I am an extremely dissatisfied customer and expect someone in your company to come up with a permanent solution to this problem. It does not make sense that I am paying for a premium service, with line insurance, etc. and have to deal with an intermittent problem such as this.
