No, I can’t. I don’t own the postal services or the shops, so it’s not up to me to promise you a date that you’ll receive your items. For made-to-order products, bear in mind that production time frame estimations given by sellers are generally just estimations. They are subject to delays. Even the most reputable of sellers overshoot promised deadlines for various reasons. This isn’t something within my control. I can only ensure that they eventually get your item shipped out or try to ask them to cancel your order and give a refund.
