Copies of my last bill

I seem to be having problems sending copies of my last bill via gmail.for proof of exit fee’s.i have tried doing screen shots and sharing to my Gmail .they will send them to bulb but you cannot open them up to see the screen shots
.they are jpgs and only using a small amount of kbs.

Does your old supplier not make a complete bill PDF available that you can just forward on?
