(UK) Selling a £20 top up voucher any network {paypal}

Hi, I am selling a £20 mobile phone top up voucher for £15 paypal. I am doing this because I need some cash in my paypal account. I will go first if you are very trusted otherwise you go first. Please only post below if you are interested in buying it and not just to bump or spam. I will tell you the code over MSN.
