> Online cancellation (compared to telephone cancellation) is like the latter, not the former.

Wait, what? No, it's like the former. How do you know these agents handling your cancellation weren't assigned to handle similar cancellations from other deaf customers? How do you know the representatives don't have to go through extra procedures (such as documenting and obtaining authorizations for the non-standard cancellation, or bothering more reps to figure out whom to forward the inquiry to) that wouldn't take them far more time than it would take the phone agent? Meaning you could well be taking up a resource that was reserved for disabled folks, slowing down the responses for them in the process. Heck, even if the amount of time spent isn't any more than for a phone call, it's likely to be a separate set of agents handling these special requests than taking calls, meaning you'll still be slowing down this service for those who actually cannot use the phone.

What I find baffling is that neither you nor anybody else is making the most compelling counterargument I can see here, which is that cancellations aren't time-sensitive, so a slower reply would be unlikely to do anyone much harm as a result of slow service. Meaning it's one way you could argue disabled people are not suffering any tangible harm from slow replies. But to argue that it doesn't even affect the service provided to them in the first place is bizarre, especially if you think about what would happen if tomorrow everybody decided to follow this advice and do the same thing.
