Larian DID indeed give HappyShops the instruction to ship out the CEs on the 14th (exactly as they also advertised on the shop.larian.game pre-order website)... they didn't lie about that.
That HappyShops messed up these instructions and managed to still not have all CEs shipped before the 22nd, angered the support people at Larian as well... so even though it was Larian who hired HappyShops, Larian themselves did not INTENTIONALLY provide us with false information... in other words, it's not correct to say they "lied" about this.

You're right, though, it would have been a lot better if they had started shipping a week earlier (especially for the overseas shipments)... no idea why they didn't. Maybe some of the items weren't finished before that date?
