Discovery Insure - help please?

Initially the very best service received on my Claim with Discovery Insure, I was issued a Makro Voucher and went shopping. Exact Items could not be purchased as Discovery was quoted on replacement Brands by their service provider. I then contacted Discovery and explained that the items claimed could not be replaced with the Makro Voucher. I agreed that Discovery cancel the voucher and approve the claim with their service provider. After approval; I contacted the service provided and asked why the items is a different brand than to what I had. Supplier had no stock and what was quoted was what was available at the time. I asked about one specific item claimed that was not a complete system. Discovery Service provided said that they quoted for the receiver only and not a complete system.

This was my exact concern with the Makro Voucher.

The only issue is that this is not being resolved, numerous emails not answered. Calls have been made but was told today that no notes was made on the system. so if there is no notes, there is no proof.

Discovery please help?
