Shocking service- no response

I am at my wits end with Bankmed. We submitted claims last year which have not been processed. I sent emails to enquiries@bankmed and get no response. Out of pure frustration I post a complaint on the Bankmed Facebook page and get a response from Meera Moonilal. I re-send all the documents to her several times and each day there is some other document that is missing. I do not get any further response from her when I ask if everything has finally been received. No response! The claims still have not been processed. We are pensioners and have paid a lot of money from our pockets. Please can someone competent process these claims.
