Services suck. I called a head of because I was moving Thursday and they told me bo available appointments until Sunday. Sunday came boone showed up. I call they tell me it was the Saturday before. But I was home Saturday noone came. They tell me ok Monday from 4 to 6pm  again noone showed up and they gave me another date when am working. So I called again noone gave a dam, now I have to wait until Sunday yet again. More than a week late and of course I have to pay for them to come out. No thanks am so over Xfinity
