Hi CaitlynGriff,
Thanks for your post and welcome to the forums. It's great having you on board with us in the Community.
I'm sorry to hear that you were not given a choice of dates for the delivery. If joining directly through Virgin Media then we would give you a choice of dates however if you've joined through a third party then they may automatically schedule you in for the next available.
Once you receive notification from Yodel, you will be able to reschedule the delivery directly through them.
Please let us know if you have any further issues.
Thanks,
