Why have I been charged for giffgaff-to-giffgaff calls or texts?
It may be longer than three months since you bought a goodybag or some credit. Check on your dashboard under, “recent usage” to see when your free giffgaff-to-giffgaff calls and texts expire.
Or, it’s possible that the person has left giffgaff. They may have switched networks and taken their giffgaff number with them.
If you’re stuck, ask our friendly community helpers. They’ll give you some great pointers.
