Worst Insurance Company

Nedbank Insurance: I have put in a claim against my swimming pool in May 2019, they sent a the POOLMAN and an Assessor to have a look at why the pool is losing water. Both the POOLMAN and the Assessor did not do any tests, they merely looked at the pool and said it was the wall of the pool and that was not covered by the insurance. So i had my pool renovated and repainted at my cost of R8500.00. After doing all that the pool still leaks. so i reported a new claim in September. A new pool company has been out to have a look and they have detected that the leak is on the return line, an assessor has been out to see it. they have still rejected the claim stating that the pipes which are under ground was not installed properly. the pool is 6 years old, how am i to know what happens below the surface. i have made numerous telephone calls to Nedbank Insurance, they never get back and let you know the status of your claim. the worst insurance compay to deal with and they are not the cheapest.
