Hi @Mark_j98 ,
If you bought online and things are already completely not what you understood and expected, I would highly recommend to consider cancelling in the initial 14 day period.
Did you intend to gift just a mobile, or the mobile, SIM, and your services in managing the account to the lucky recipient?
If you want to gift a device, it would be better to purchase an unlocked device outright from a retailer which allows change of mind returns (i.e. most others).
If you want to pay the minimum term contract, all additional costs and roaming costs, and spend the time managing the account on behalf of the giftee, this seems to be what you've put yourself on the hook for with the actions you've taken.
If the above doesn't sound like what you intended, it would be better to cancel an online bought contract, but you would need to check further on whether there would be any valid basis to cancel a store bought contract (e.g. contract complete not as described and verbally contracted).
