Query: Worst shipping company ever was used

Amazon keeps telling me my package was delivered, but I've been on the phone with the delivery service "Lasership" for two days. I ordered one day delivery on Monday and it's now Friday. I'm sitting here with a bleached head waiting to use my dye but woops, it's still not here!If I had realized that ordering one day service off of an amazon prime seller meant wasting my time waiting around for some piece of crap delivery service (instead of the USPS or UPS, why?) I never would have ordered from here.Here's hoping I finally get my hair dye before I have to go to work all weekend looking like a complete idiot.
