False Advertising - *******

Placed an order on 15 March, which would have been delivered within 3 working days. We are now on the end of the 7th working day and I am still in the dark. I have spoken to the call centre twice, and keep getting reference numbers and promises that someone will contact me before the end of the day, which obviously never happens. Why do you state that my order will be delivered within 3 working days if it is actually going to take 2 weeks (or more I guess)? Order number ********** 92. I have paid for this, so you are lying and *****ing from me. I strongly suggest you make sure that I have my order by tomorrow.
