What made you think that.
You can have credit and a goodybag at the same time.
See the pic above
I think you must have clicked on the dhange your bag early icon as that would cancel your goodybag.
All you do is click on the add credit icon on the right
All the best Bob
Hi @mariagibney giffgaff does allow you to have airtime credit as well as a goodybag, otherwise you wouldn't be able to make those calls/texts which weren't included in goodybags, eg international or 0845/7 numbers.
So you should double check what happened by
dialling *100# for your airtime credit (payg) balance.
dialling *100*7# for details of the remaining allowances in your current goodybag and when it expires
