Go to a bodyshop. Your dealer may be different, but mine simply refuses every time I bring it up with them.
Shop around, find a bodyshop with good reviews and get quotes. Avoid "mobile resprayers", while they're good for fixing stonechips and single panels, you need a proper bodyshop for the space to do all 4 arches.
Expect it to cost a couple hundred quid tho...
