My internet was disconnected after 2 days of being active because of the previous tenants bill

I moved into this place June 28th and set up that weekend online to get internet because I do online college and my equipment came Wednesday the 3rd of July set it up activated it that Friday two days later my internet was disconnected no warning no nothing and I have been fighting ever since and I'm not related to the person that lived here before even though we have the same last name I'm not from around here there's a lot of people with the same last name in the Kansas City metro area and I've proven that I've sent to my lease I can't tell you how many times do the online Link they sent me I went down to the store did that and they closed my ticket no warning no explanation no nothing still no internet and I have been fighting now also with the college I do online college with fighting to keep my financial aid cuz they're about to pull it because I haven't been able to do my classes this is ridiculous these practices need to be done a little bit differently because it's messing with people's lives when this type of stuff happens I really need help I need internet you're on the internet provider around here and if not I'm [Edited: "Language"]. I'm disabled I don't get around very easily don't have a running car and it's just been a nightmare a big big nightmare. And another thing is when it first got disconnected the first agent I talked to told me it's cuz I had a past due bill which it wasn't past due it wasn't due till July 26th but I went ahead and paid it cuz they said it would be turned back on and still nothing but still have my money.
