Call 0333 338 1082

Hello, I'd like to cancel my Three subscription, please.

My name is [your name].

The account is under [your email / account number].

Could you confirm the cancellation date, that no further payments will be taken, and send me written confirmation by email?

If a refund is due for a period I've already paid for, please could you confirm the amount and when it will reach me.

Thank you.
