Are you info safe at Discovery?

I was contacted by a case worker from Discovery a few weeks back, due to ill health and chronic conditions, she stated that there is additional benefits I was not aware I could use. She had all my details and conditions, she stated that she will forward me all the additional benefits. I have not received it yet. Due to a stroke I had difficulty in writing her name, I contacted Discovery earlier and spoke on whatsapp with Bongolethu to see how far they are in compiling the mail. I was informed that there is no interaction on the system between myself and them concerning these benefits and cannot tel me who phoned me and they can only forward me a mail regarding the benefits, the problem is that is not what I was promised, as I was promised a list of approved doctors in my area as well as the updating of my diabetes machine and test strips. The question now is, if the are not able to see who contacted me any person at Discovery could contact me for any reason they see fit, make promises to me and not be held accountable. I will be referring this to the ombudsman if I do not receive acceptable feedback regarding the call and the promises made to me
