申述模板
Dear giffgaff Team,
I am writing regarding the email I received stating that my service (mobile number ending in 3047) will be disconnected due to extended use outside the UK.

My account/number is 7768423047.

To clarify my situation: I original subscribed to your plan while studying in the UK. After finishing my studies, I returned to China where I now reside on a long-term basis.

Since you have indicated that it is your final decision to terminate my service due to long-term roaming, I would like to request a full refund for any remaining credit or unused plan balance on my account.

Could you please confirm:

The exact refund amount I am eligible to receive.

The expected timeline and method for processing the refund back to my original payment card.

(Note: If there is still any possibility to keep my service or SIM card active without policy violation, I would prefer to keep it. If not, please proceed with the disconnection and refund.)

Thank you for your assistance.
