Pathetic Service

More than a month ago I submitted a claim with discovery for my stove, someone came out to inspect the stove but did not really do anything, they literately only looked at it for 2 seconds and then left again. The claim is then rejected and the reasons are "Wear and Tear" and also "its a fixed stove" so I have to claim from my building insurance, after a long argument they realized they made a mistake and that the stove is not fixed but a movable item (This already proofs that they have no idea what is going on with the claim), the claim has then been escalated to another department. It has been more than a month and every week I have to follow up and then get no reply, not a phone call, no email, nothing. I really do not know what to do anymore. I am however not going to leave it there and will make sure that this gets made public.
