Is Giffgaff's 3-month or 6-month contract?
Bosses who send cards write that they can activate the card once every three months for 10, and get their money back in 15. Another boss writes that they can only activate the card once every six months for 10, and get their money back in 20. It is confirmed that if you spend 10, you will get your money back in 20 (before August 31). How long does the protection of the number last? What tools do bosses use to remind themselves not to be收回?
