Welcome to Vodafone Community
Basically the story is I have a 7 month Huawei p20 that suffered screen burn, the phone from day 1 has had a case and screen protector fitted so is immaculate condition.
I took it back to my local vf store and the chap said yea should be no issues you can see it's mint condition. Anyway 10 days later I get a phone call from vf repair centre saying its been internal damage that caused and supplied me a repair quote to fix.
So I said the phones never had damaged and the screen on the outside is immaculate so how's that.
Anyway there refusing to fix, can I demand it goes to the manufacturer for a report because I simply don't trust vf, think thet maybe just trying to shirk out if the warranty.
I believe it would be up to you to ask for your phone back from Vodafone and then engage directly with the manufacturer.
Damage insude can occur from for example a drop that's not caused any damage to the housing or the front or back of the phone because its had a case on it etc.
I'm not saying that you've dropped it but mention it as an example.
I wish you all the best with this situation.
