Slow response on urgent issues

I have two issues with Discovery Insure which I will discuss below: The first is I contacted their call centre two weeks ago to query my my refund amount due to the lockdown. They calculated it at 15% instead of 25% as I drove less than 250km in May.. They said they will contact me in 48 hours last week and I am still waiting for feedback. The other issues which is more serious, my car battery died in the lockdown and I replaced a new battery with Audi. Last week I saw that there was a low battery warning. I took the car into Audi and they said there is a power drainage on the battery. I called Discovery on Saturday and they said that they need a battery drainage report which I sent them. On Tuesday I called in again and I spoke to Anna who said C Track will contact me yesterday and she will also follow up with me to see if they contacted me. Still have not received no contact, contacted them on Facebook also but no response on my issue. Audi has asked that the tracker be disconnected so that they can see where the drainage is coming from on the battery. If I have another dead battery and if it is due to the tracker I will be holding Discovery responsible as they are taking their own time to resolve this.
