You must have purchased both at the same time and from the 11th February.
Get a pair of Beats Flex on us when bought with an Apple Watch Series 6 between 11 February 2021 and 24 March 2021 directly from O2 in the same transaction. If Apple Watch is returned, the Beats Flex must also be returned. Subject to availability, while stocks last. Beats Flex may be delivered separately. Terms apply, see o2.co.uk/terms.
You could now return the first watch and reorder, but there is no other way to get them I'm afraid.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
Please select the post that helped you best and mark as the solution. This helps other members in resolving their issues faster. Thank you.
