Help with my NOW services

I need help with my services. I have now home internet and two now mobile lines. They are paused because the bill didn't get paid this month. I have had them since last July and they were paid with the card listed in autopsy. The problem is that when I try to update my payment method, it says there are no NOW services registered to my account. When I sign into the app it shows home internet and two mobile lines. When I click more details or update payment or restart autopsy, it says no services registered to my account. I have called customer service numerous times, and they can't find any services registered to my account. I have been to two different xfinity stores and they couldn't find any services either. But when I tried to start new NOW services, it said there are already NOW services at my address and it wouldn't let me go any further. All I want to do is update my payment method and restart my services. It's hard to believe that a company like xfinity can't help me at all. At one store, the manager was trying to help me and he called customer service and after about 15 minutes of them trying, they told him that they couldn't do anything for me. I've been told the same thing when I called customer service. The manager at the second xfinity store said my best bet is calling customer service and hope that I get connected with a tier 3 agent, but that was not very likely as there are only about 75 such agents in the whole company. I don't really know what to even think it's hard to believe that the managers of two different xfinity retail stores, and several different customer service agents would just tell me that there is nothing they can do. I'm so tired of trying to get someone to help me. I don't even know where to lodge a complaint. If I had more money for deposits and service charges I would switch to another provider as fast as I possibly could. Unfortunately I don't have any choice but to try and get my services restarted. Not having internet is bad enough because my kids are nonstop complaining. But not having the phones is worse because who knows what calls we have missed as there is no landline at our house. I have seen on other posts here that sometimes employees of xfinity answer questions and I am hoping someone like that can help me because I don't know of any other options.
