No support whatsoever

I have a package that was shipped on the 21st and on the 23rd I was called regarding the import taxes and duty. Till date, I have not yet received the email with the invoice in order to pay. I phone 3 time a day, I have send numerous emails but nothing. I paid a LOT of money to have my package shipped via UPS as this was supposed to have reach me within 2 working days. I expect that invoice to be in my inbox URGENTLY and I expect a discount as well as I pad for a service which is not being rendered, and delivery is deliberately being delayed by you.
