Wish complaint: Delivery

Ordered a jbl wireless speaker when ordering it stated dispatch 3 to 5 days as I desperately needed one but on checking I’ve got to wait over 8 weeks for delivery I find this totally mis leading it’s been at the China’s dispatch hub for the past 5 days and hasn’t moved . I would have quite happily have paid another 20 pound for a seven day delivery service now I’ve had to buy one off of amazon costing 200 plus I’m very annoyed and can’t understand why if coming over by plane am I having to wait 8 to 10 weeks delivery and even when I receive it don’t know if it will work correctly as re furbished. I’m very annoyed and not that satisfied with delivery is there anything you can do to speed up the process and find why it has been sitting in a warehouse for 5 days plus and when it will be arriving if coming by plane as shown on delivery ?? Thank you
