poor customer service

2nd december i first reported the poor service we got from nedbank insurance staff and their service providers. we had an issue with our electric fence and lodged a claim. it took them weeks to come back to us informing us that we we not covered. which we accepted and they gave us reasons but our complaint was that we had to phone the nedbank staff ourselves about 10 times - and their service providers and no one ever called back as they kept telling us. our perimeter fence was not working for weeks and weeks as we waited. the service received was pathetic. since then i have mailed various people on probably 3 occassions and not one person responds. it has been 3 months now and they do not even have the decency to reply.
