Set up payment arrangement; service still suspended

I set up what I thought was a payment arrangement (I've done this several times before in the past) and never had an issue like this. I called yesterday to ensure that my service would not be disconnected because I got a text message about it. I told the agent that I tried to set up the arrangement through the Xfinity app and the automated system on the phone and it kept trying to do it for April 26th not May 26th. The system then said "due to technical difficulties, we were unable to set up your payment arrangement." I told the agent what it said and Cassandra told me that the only thing they could do is notate the account. I wake up today to no service. I get on here to speak to someone just to be told that I set up a scheduled payment not a payment arrangement. Trying to do that now so my kids can go to class. I need my service restored and the ability to set up a payment arrangement  please help me!
