How do I find Airtime Rewards credit on account?

[Queenalisun04]

Hiya, I have been using Airtime Rewards and have redeemed around £100, but I have never checked where it has gone. I signed up with my O2 mobile number, but how do I see that the transfer was made to my O2 account? I cannot see it on any bills . Does it count against the airtime or the device plan? Thanks!

Counts towards airtime and should show as a credit on your account

Can be confusing as transferring £20 would show as -£20.00

You next payment would be reduced by that amount
