Cell phone upgrade

Xfinity is the worst company I ever had to deal with and they mistreat their customers. I am going to contact the Better Business Bureau and let them know about Xfinity’s price gouging practices. Throughout the years, I have paid thousands of dollars towards my bills with them and every single month. I moved recently and was charged several fees making one months bill almost $800 which I paid $600 towards. I went to upgrade my cell phone, which was paid off in two years and I always paid my bill and they refused to give me any type of credit. They know that I would pay it every month, but they still refused because of one month. I paid $600 towards that one month but the reason why I didn’t pay the other 200 is because I’m trying to have the fees waived. It’s ridiculous to be charged that much money in one month. I’m going to tell everybody all over the Internet and all my friends and family to not use Comcast and switch the Verizon. I’m sure Verizon knows how to treat their customers. I absolutely despise this company and advised nobody to use them.
