Discovery Insure Claims department useless and never responds to my mails and phone calls

Before Covid 19, I had no issues with Discovery Insure but since they have limited staff working, the service is atrocious. I have raised my claims issue numerous times and receiving no joy. No one ever gets back to me. I have been waiting 3 weeks to be refunded for a plumber I had to pay out of my own pocket - Amanda from Discovery requested I appoint my own plumber as the plumber Discovery originally appointed purposely broke my plumbing pipes to try put in a big claim. I also put in a claim to have my ceiling replaced after geyser pipe leaked and needed to be replaced. My fascia board also blew off when we had a strong wind about a month ago. The last person I spoke to at Discovery, informed me that the lady in charge of my claim Nombulelo had mistakenly closed the claim without appointing the contractor(that had already been to my house to assess ceiling and fascia board) to come replace ceiling and fascia board. With her closing the claim, I am yet to get refunded my R1875 I had to pay my plumber to replace leaking geyser pipe and replace broken plumbing pipes the plumber Discovery appointed broke. I keep emailing Nombulelo and Discovery Insure but am still waiting for someone to contact me to make payment to me and get my ceiling board and fascia board replaced. Absolutely disgusting service!!!
