Pathetic service from Nedbank Insurance

I logged a claim with Nedbank about my swimming pool motor, that just stopped working. An assessor came out 2 weeks ago and assessed the motor and left. I called Nedbank this morning, 2 weeks after the assessor has been to my property and I get told my claim is rejected. No one at Nedbank Insurance took the time to call me and advise me that the claim is rejected. I pay a substantial amount monthly for insurance and I expect my claim to be honoured. I have been a client with Nedbank for over 30 years and this is the service I receive. I get told that it is due to wear and tear that my claim has been rejected, HELLO a motor has to run to do what it is supposed to do. This is unacceptable and I need my pool motor repaired.
