No Internet for a week – please help!!

I'm really hoping that someone can help me here. I have had no Internet service for the past week. My power went off on January 25, just like hundreds of thousands of people in my state, did due to the winter storms. It was back two days later on Tuesday the 27th – one week ago today. However, my Internet has not come back. When I finally got someone from Xfinity technical support on the line yesterday, they told me this was a "planned outage" that began on January 25 and would end at 9:30 pm last night.I could not believe this is what I was being told by your technical support team – that my Internet issue was due to a weeklong planned outage that customers were not informed about in advance and just happened to coincide with a power outage. I repeated it to make sure this is actually what he was telling me. Of course the "planned outage" did not end last night and I still have no Internet, except the unreliable Wi-Fi I'm getting through the mobile hotspot that your team had me sign up for, lying to me about the cost for this. (That is a separate matter that I've taken up with billing.) In any case, how can I get someone from technical support out here to figure out why my Internet is not working when other people on my block, including my next-door neighbor who I share a garage with, has service??
