Dropped by GS3, cracked the screen

Dropped my GS3, cracked the screen.

Few weeks later and the battery would take nearly 5 hours to charge from a few % to full.

Took it into my local 3 UK Store for the screen to be refurbished, and as an aside let them know of the charging problems. NO OTHER PROBLEMS WERE APPARENT...AT ALL!

I was quoted the generic £75 to fix the phone, which will be added to my monthly bill.

However, on Monday (4/3) i received a letter stating that they can't fix the phone due to "water damage".

Now i can categorically state that at no point has my GS3 been submerged in water or been out in the rain - in fact the only "water" it could have come into contact with is the sweat from my hands!

Anyway, i went to the store this morning and they gave me an email they had received from their Repair Centre stating that the Main board had failed its RF tests.

As a result of this, the guy said that the phone will only get fixed under my insurance.

I grudge claiming on insurance if the fault was not down to me, although if i have to, i will.

Anybody have any advice?
