How must a deaf client contact Santam S.O.S number??

Hi there. I am happy with you guys, but phoning to S.O.S contact number is really unproductive on the basis that I am deaf. My broker pointed to me that there is a S.O.S. landline number, but It severally restricted me, because there is NO other option such as S.O.S WHATSAPP number that will accomodate deaf clients. I hope that Santam takes consideration to accomodate the needs of people with hearing challenges that cannot contact the S.O.S number to Santam.
