Just had a look at the terms of the warranty and I will be contacting lexus again as it clearly states that TWG administer the warranty but the warranty provider is Toyota. Nowhere does it state it's an agreement with the dealer!
I feel lexus customer customer service are just uninterested, I even had to point out that in his reply he refererred to the fault as an exhaust pipe and not a heat shield..
