Discovery insure takes a week to even acknowledge a house claim and then asks for photos

Discover insure covers both my house and contents, when my geyser started leaking I asked them if it was covered, they said it was, without telling me that i needed photos of bath the old and new geyers to put in a claim. It took their consultants a full week after I had sent the invoice for them to ask for photos. This is just a further delaying tactic.
