Poor Customer Service

I received very poor service from Santam Insurance. Spoke to 3 different consultants, unable to resolve my query. They seem to have no understanding about my query and what I was trying to relate . I spend 35 minutes and had given up. They failed to understand and assist me. My query, I submitted an invoice for additional solar panels to be added to my building insurance. I received new premium updates from 2 different consultants on the same case. The premium I received from both of them differs. I also requested for an updated policy of the adjusted premium. I failed to receive one.
