Zero service

I started an investment journey with Discovery through one of their financial advisors. After 6 months with it I wanted to see how it's going and discovered it's growing at a negative rate. I tried to speak to the advisor with no success to a point where I start reversing the debit orders to get their attention. This happened around May and I still have no joy. I make calls, they want to verify me with an otp that comes hours after the call, promise to call back which they never do. They even send a review request that I rate 1 as they still see nothing wrong with their customers not being able to get hold of them.
