DISCOVERY HEALTH DISPUTE QUERY FEEDBACK

I am struggling since 9 April 2020 to get feedback from Discovery Health regarding an dispute outcome. I have send various emails to follow up on my queries that I had with their decision of the outcome. On 28 April I received an email saying the query has been referred and I must allow 2-3 working days for feedback. I received no feedback. Followed up again on 13 May and still have not received any feedback. Do not thinks this is the way of treating a customer fairly at all. I am not used to struggling with Discovery Health at all. I have always received very good service from them, but his is really concerning.
