Skynet worst service EVER!!

I placed an online order from the UK, and the service received from Skynet was/is horrific! The order was placed on Monday, 1 October 2018, with the goal of having it delivered before Wednesday, 10 October. (an order I placed on the same day at another UK company that uses UPS for shipping, delivered on Thursday 4 Oct already). To get the parcel through customs was bad already, I received an invoice on monday (8Oct) only, paid and sent proof of payment within 30 minutes, and then the big silence..

I tried sending emails, tried calling, nothing. No way at all to figure out where my package is or when it will be delivered. Online tracking shows it was released from customs on 9 Oct, and nothing since.

When will I get my package??
