Damaged brand new watch

Brand new G-Shock watch 24 hrs old. Sprayed this maximum formula on my arm and it reached the side of my watch. Had a chemical reaction with the silicone/rubber and it’s irreversible. Contacted the company regarding this and they fobbed me off telling me it’s not compatible with plastics and synthetics yet it doesn’t state rubber or silicone or even synthetics on the label. Avoid this at all cost as the company are vile - I asked for reimbursement and they have sent me lies about their labelling as you can see on the photos attached nowhere does it state rubber/silicone . All I am asking for is the cost of the watch as a replacement and they are not interested. Disgusting company to deal with. Never again will I use or recommend this brand
