No answer from Imports Department

<p>I purchased some clothes from an online show in the UK and received an email from Muhammed Hassen on Monday advising that I need to send my ID number in order to receive an invoice. It is already Wednesday and I have not received an invoice. The clothes are due to be delivered on Friday the 4th of August. I have sent him an email today without any response. I tried calling him on ********** 902 and also no luck. I called Skynet's reception to transfer me to someone who could assist but when they transfered me twice when I phoned there was no answer. I did notice that if the custom duties aren't paid within 7 days the goods will be returned. 7 days will be on Saturday/Sunday. All I want is just an invoice in order to pay and for my goods to be cleared with customs. If it is not within the 7days, will Skynet refund me with for the money I paid for the clothes as the delay is with them?</p> <p> </p> <p>All I need is just for the Imports department to do their job and send me the invoice.</p>
