Not Deaf-friendly : Email remaining no answer

I am Deaf, I am looking for Deaf-friendly communication channel with international removal company and ensure everything going smoothly without miscommunication. However, I have been trying to place orders to ship from South Africa to Australia. I have been having problems with the emails remain unanswered. If Seven Seas are this unprofessional in dealing with potential Deaf customers, I won’t place an order! Please contact me by text message or email, not phone as I can’t hear.
