Terrible!!!!

I'm so upset, made an order on the 23rd of November for 2 pairs of sneakers online, which were xmas gifts . I emailed them 14 working days later informing them I haven't received my goods as the site stated it would take around 5 working days. I got an email back stating the address on my invoice was wrong and the courier company has decided to send it back to the warehouse and I won't be getting my stuff, I emailed them back asking who's fault was that as I have the invoice and the correct address is on it, that email was ignored. I get an email today, the 11th of December informing me that my parcel has been delivered and I'm all frantic cos I didn't receive anything, so I call them and then I get told, there was multiple attempts to deliver but to no avail. And I explain to the guy, I'm home everyday, all day and then he states, they couldn't find the area!!! What nonsense it that, I don't live in some remote rural area! And when I ask about the email, he says it was a mistake, it was meant to say, it was returned and not delivered. I don't understand what kind of Micky mouse operation you'll are running. I'm so disappointed, I spend 1000s with you guys but no more. The way you'll handled this was all wrong. Oh and when I checked my details from the courier company, I noticed now that my cell number has an incorrect digit. But again, who's fault is that? My details on the site are correct, how do I not get my stuff at the discounted price because of incompetence on you'lls side????
