Vitality Drive 3.0 **** - Changed The Cashback Without Notifying The Customer

I want to lodge a complaint about Vitality Drive 3.0. I called the Call Centre and spoke to Kwena at 10:53 to check why my Vitality cashback was low. I was informed that Discovery Insure changed the rate for Home Insurance to R300000 without notifying the Customer. This is deplorable Customer Service and ********* behaviour.
