1st email arrived exactly 14 days before top up due.
Let me know if anyone wants to order one, have referring code which give you and me extra £5 credit, when you order sim.
My top up is due on the 17th - as yet no emails.
May be too late, try TCB (topcahsback.co.uk) - I got £5.25 back! :)
Anyone got a referral code
