IPhone 6S replacement just 8 days old?

I bought an IPhone 6S off someone with official Apple receipt. It had started to give me problems with the ear speaker. It sounds like a blown out speaker. I know it's under warranty and it's just 8 days old so also under 14 days full return warranty. I don't have receipt as I post it and can't find. Apple is for sure going to replace my phone but is it possible to get a different colour as I'm not happy with my current colour as well. I'm not being cheeky but if I have still 6 days to change my mind. Would they mind if I don't have receipt. Any ideas?

Best to contact the store it was bought from, to find out what their policy is for returns without a receipt.

You have found out why they sold it, The original Warranty is non transferable so even if you had the original receipt you still would not be covered, Get hold of whoever you bought it from As soon as possible
