Discovery Disappointment

I am very Disappointed with discovery Insure. we had a cable theft with electricity in my area and when the problem was resolved we found that our gaming PC,s would not come back on. We logged a call with my Broker and Discovery and asked them to send a technician out to come have a look. the reason we asked for a technician to come out is because I have all my keys stored in the tmp on the board for my cripto and also have sensitive information on the system so did not want to send pc away.Discovery sent a technician who came and checked the PC's we found that both pc's were blown the power supply, Main board and graphics card. Discovery then sent me an email to say they have to send my PC's away as they need to do a more extensive check. I have told them that the PC's cannot leave my premises without me been there as i have sensitive information on the HDD and my crypto keys are on the Main Board. I then paid for another service provider to come out and do an extensive report which was sent to my broker and also uploaded to discovery. They have rep**** back again and said they need to collect the PC's. I pay discovery over R15000 P/M and have every extra service and topup they have to offer so i dont have problems should a claim arise and it looks like they are trying to find a reason to not resolve my claim. I am very disappointed with discovery and have now asked them to cancel all my policies as well as my Medical aid and Discovery Bank. I am also getting my family and friends to do the same so they don't get caught in the same trap. I am getting the ombudsman involved now as well to assist me with the claim.
