Shockingly bad service!

I logged a claim on 06 June for electronic equipment that was damaged due to a power surge and after paying the excess on 01 August once the claim was approved, I received delivery of the insured goods. My husband advised me that the parts replaced were incorrect and sent the items back to the supplier whereupon I asked Discovery again for assistance as the claim was not complete. It is now 06 September and I still have no help from Discovery and no-one is contacting me to advise what is going on - this is unbelievably poor service and I am looking for an alternative insurance company. Well done Discovery, you've just lost another customer!
