I didn't get £5 credit which I should as my friend activated their gg sim
You appear to have been a member for a long time, so you wouldn't have got the £5 bonus for a friend activating with 42 days of your activation.
You should get 500 payback points, but these won't show on your account until after 5th of next month. Payback is paid out a few days after 5th of December.
Perhaps you can give us an idea of timescales - when did your friend activate their SIM?
Did they see a question about your phone number - that would indicate the SIM had not come from you.
