How does this work for deaf or hearing impaired users? Surely even in the US there must be a way to cancel a subscription without having to speak to someone on the phone?
When you call via a TTS gateway, a certified transcriptionist for the deaf or (now) a computer program that does speech recognition will transcribe what is said by the other party to text so you can read it and speak out loud what you type exactly. There’s quite a few regulations around this service, although I’m sure it’s developed since I last looked into it.
There are also special phones or phone apps many deaf people have that do live captioning. CaptionCall is one common brand.
