No online order - flippant helpdesk response

I ordered an item online, it said it would take 3 - 5 days to deliver and I'm still waiting for any kind of response or delivery 5 days later. I mailed their helpdesk and the only response I got was from a lady called 'Lesley Kurucz' including 2 other employees on the mail (she didn't even address me directly) and said 'Please revert back to Bradley asap'. Since then, not a response was heard from all 3 employees. I'm assuming at this point, and from the other complaints here, that I'm likely not going to get the item I paid over a grand for. Will certainly never order from them again and advise against doing so to other people as well.
