Pathetic Service from Discovery Health

I do not know where to begin with the pathetic service i am receiving from Discovery. I have made and received numerous phone calls from your consultants and senior management regarding my claim .i spoke to a manager on Monday and today when i did my follow up there is no record of my conversation yet i received an email on Wednesday in this regard. Received a phone call from the CEO office from a very rude and arrogant individual. My query has taken over 2.5 months to resolve and not resolved to date. I was then told that my query would Hopefully resolved by tomorrow .Totally unacceptable. I was in the amidst of a sentence complaining when the man said Good Day and cut the call .This is very unprofessional. Told on numerous occasions query is been reviewed and escalated. Who is the query been reviewed and escalated by because nothing is been done about it.
