Catch-22: Requiring Phone Calls to Set up a Relay Service for Users Who Can't Make Phone Calls?

I've been trying to register for My Sprint Relay, because I have sensory issues, including hyperacusis, and I can't make phone calls.

Once I complete the first part of registration, I get an email which, after some identifying info, states:

Sprint Relay Customer Service has received your registration request. To complete the FCC required verification process, please contact Sprint Relay Customer Service through www.sprintip.com and click on the link "Need Help? Call Customer Service" or contact 800-676-3777. A representative will be available Monday-Friday from 6 AM - 11 PM CT.

Thank you

If I click the "Need Help? Call Customer Service" link, I get an email, but each time I write to that email, I get something to the effect of:

Hello [name],

To complete the FCC required verification process, please contact Sprint Relay customer service through www.sprintip.com and click on the link "Need Help/" Call Customer service or contact 800-676-3777. A representative will be available Monday-Friday from 6am-11pm CT.

Thank you

Finally getting somewhere, but not any closer to registration:

Do you have access to a TTY or to a Video Phone? If so, you can contact us through the relay operator at 1-800-676-3777

P.S. Okay, there was also a chat option, which was hard to find because of my browser settings.

I got through on chat, and they require a drivers licence and a utility bill. I have sensory processing disorder so can’t drive, can’t bike, can’t ride the bus, and can barely cross the street because of the strobe lights everywhere. And can’t get through the bureaucracy because of the strobe lights there. Frak ableist Fcc requirements.
