DISCOVERY INSURE BAD SERVICE

I had burst geyser earlier this year. Discovery had contractor to come and and replace my geyser. Last week I had Certificate of compliants(CoC) done and a list of problems came up of the repair/replace that was not done properly as it should be by law. This could cause so much more damage because it was not done properly. I mean list of things. the quote was R8000.18 to repair it all. This mess is because Discovery contractors can't do the job right. DISCOVERY has to pay for this not me. This is unacceptable. I pay my premium every month and it is not cheap. Now i have this problems.
