Iphone 8 cracked home button not caused by accidental damage

Hi. Thanks for your reply. It was bought on 29.01.19 and came with a 12 month guarantee but the seller says it's accidental damage and will not cover the fault under the guarantee. I know for certain it's not been in any incidents and clearly a home button should not crack whilst carried in your bag! It's trying to prove that I have not damaged it myself and for whatever reason the button has spontaneously cracked without any incidents occurring. I've now found similar threads on here with this issue and Apple are constantly blaming the customer for the damage which is unfair. They need to address the problem and find out what is causing this issue. I currently cannot use the home button and have turned on assistive touch so the phone can be used. I'm not happy at all about this matter. Apple customer services said my complaint must be directed to the seller.

Full refund of cost of phone received.

Thanks for your reply but I'm positive it's not accidental damage. It was in a bag and hasn't been subject to any knocks, drops etc.

Hi, it wasn't a private sale, it was purchased from a shop 29.01.19 with a 12 month guarantee. See my reply to jorge1318. Many thanks.

Thanks again for your reply.

What other way can i pursue this please? I'm in the UK so we have consumer protection rights, is this the route I should be taking?

No but I'll look into it. Thank you.
