Voting issues in PA

PA in Westmoreland county

just probably made it impossible for me to vote. I'm disabled and I completed a request for medical absentee ballot several years ago. I called last week and was told I was good and that they were being sent out last week, I never got mine. I called today and was told I never requested one. I would have to go online and fill out a new request. I don't understand why they didn't say this last week when I called. I don't understand why they have 2 categories one mail-in-ballot and one absentee ballot and why for absentee due to medical issues they require you to constantly request a new ballot when a permanent disability status isn't going away. I don't understand why in the United States it's so freaking hard to vote.
