Disgusting service

Have been calling since 12/09/2017 for them to process a claim and its now 09/10/2017.Have been sending emails and calling and getting no response.They keep telling me that my problem can only be rectified by the claims manager KG but he is never available to take my calls or return them whenever i leave a message.Now im unable to go to the doctor because of unprocessed claim but they deduct monthly installments.Their service is appauling.
