Arrogant and UnProfessional

Let me start off by stating, that I have never been treated so poorly by a business as I have been subjected to at Discovery Health. I have submitted a claim to be paid to me on the 03 May 2018. after numerous calls and interactions, I was always ever told that they are processing my claim and I can expect payment soon. So today I called back and after being given the run around I am informed by the agent Bongi, that the claim is not valid as the invoice is copied in the email of the body and not as an attachment. Now instead of finding a solution, I am given thousands of excuses and told they are sorry as it is law. I will admit that I got frustrated and told her that I would like to cancel my membership as this absolutely poor. Now what amazed me was the level of arrogance shown after this statement. As she put it very delightful that "I will put through to finance so you can withdraw/cancel" Now the level of arrogance shown here has blown my mind as I could not believe that such an institution are willing to treat the clients in this manner and also just throw them away. I am utterly disgusted and I am certain another provider will be happy to receive my money if Discover does not need it.
