Lies, lies, lies
I have never received any email from Eden Red
Virgin is crap, be aware of any offers from Virgin offering voucher when you sing contract with them. You will never get it, and at the end end you will get message: We sent voucher 4 months ago but it was not redeem within 90 days. What a joke!!!
