Our partner Redeem (who your phone sale contract is with) is currently experiencing issues with processing this payment for you. However, we recognise that the sell my phone process is “powered by giffgaff”, so we are doing our very best to resolve this situation to ensure all members receive their payments very shortly.
We will provide an update as soon as it is possible to do so. In the meantime, please be assured that this issue is being dealt with as our top priority.
