Horrible service

I called Hollard on the 22 January asking them to increase the sum insured amount. I was told to send emails and till this day no one has gave me a feedback. I decided to cancel the policy because of the poor service. Just today I called to check if my request was done and it wasn’t. The service is horrible, I wonder what happens in the vent of death. This is wrong. The sad part i have been with Hollard for over ten years and this is what they give to customers.
