How can an inmate report a lawyer to the LSO?

Hi all. I volunteer for a program working with inmates to help connect them to outside resources. Recently an inmate has requested information on how to file a complaint with the Law Society of Ontario against their counsel. I recognize the typical way would be through the LSO portal. However, this would not be possible from inside the penitentiary.

Additionally, this inmate does not have access to outside funds (no family to put money into their account) and therefore cannot make calls longer than 1 minute. They are also not able to dial digits during calls due to inmate phone limitations (ex. press 1 for English) which would prevent them from being able to call the provided alternative number (1-800-668-7380) even if they did have money on their phone account.

Has anyone dealt with this before? Is there a potentially a form that could be printed, sent to them, filled out, and then mailed to the LSO? Is there another way the LSO facilitates inmate complaints?

Thank you in advance for any information.
