Terrible Company, look for alternative services

Absolute worst company to receive service from and to resolve issues with. My wife and I live on a fixed budget like most and have been long time customers of this company. They have continually cancelled our promotions and charged significantly more every couple of months. They also had us on terrible router equipment that would not function properly and they would provide little or no support after multiple calls to replace it. Our recent bill was the last straw, my family needed more bandwidth so I bought our one router and modem based on the required xfinity specs. I had to replace several routers because they would not work for the xfinity signal (even though they were listed as approved devices on their website) and after 3 weeks of effort, finally got our service to work. For that effort, my family received a bill of an extra $100 dollars because we had a apparently had a perk with our old terrible modem where we had unlimited data but lost that perk with our personal modem. This was never relayed to us, even when communicating with them at the beginning of the switch. I do not recommend this company, I do not enjoy using this company, I am a longtime customer looking for an alternative as we speak and I will gladly tell any potential future customer to look elsewhere.
