Refund and poor communication

I have cancelled the Insurance on the 30 April 2020 since then I have not received my refund for May that was deducted on the 25 April.I have been following up with the call center they keep on it will be processed. Now is June still waiting for my refund. My policy number is ***. I have cancelled the policy because I was 10 months with Budget and they increase the premium with R300 without any notification. When I call to understand why the premium has increased so much and I wanted to negotiate with them the increase because the value of the car is depreciating on a year basis.The gentleman from budget he said he will come back to me after three days with no fees back I cancelled the Insurance. I feel like they don't take me seriously and value me as a client and I just cancelled it.
