Premium to be raised

I was contacted via email by Daphne Govender. She informed me that my premium was about to increase because she was unable to contact my previous insurer. After that I sent the policy schedule of my previous insurer to her and requested her to contact me to confirm that my premium would stay unchanged. I phoned Discovery Insure twice to ask them whether the premium was going to stay as is and whether Daphne had managed to contact my previous insurer. Each time they told me that they were unable to contact her, but would send her an email to get back to me. To date I have had no communication from Daphne. I find this unsatisfactory. I need to be able to resolve issues on my policy without having to wait for weeks on end.
