Service Centre Broken

I have opened a new account with FNB (Channel Islands). In order to verify my online banking registration I have to contact the service suite. Since I am hearing impaired, I sent them an email explaining my disability and requesting assistance by email, and received the standard automated reply giving a case number (CAS-***-J2F8Z4). Since then there have been no fewer than 5 calls made to my phone, and no email assistance despite the fact that I have sent 2 other emails further explaining my plight. I am sure stupidity of this order cannot be human in origin and is a result of an ***********ly programmed robot. Please assign this case to a human being who is able to apply a degree of intelligence to his work.
