I have had Comcast for about 1 year and a 1/2 in FL. And I have called them about problems with my internet at least 17 times.
And each time they fix it and 2 days later it's not working again. It's gotten to the point of me not even acting friendly on the phone anymore. They never come out to look at it, they claim that there's something wrong with my computer. Then they change it up and say it's because we don't have a USB wireless adapter.
Which is dumb because we get internet now and then. So because they don't want us to leave they give us a small discount on the bill. Which is the only reason why I still have Comcast to this day. I wouldn't recommend Comcast just because all of the *** I went through and still going through with them.
I will probably drop them as soon as I think the discount isn't enough. ( Probably in a month)
