Bad service & communication

I placed an order 2 weeks ago for an event that is happening. After the online purchase I called to confirm the order and the deadline and they confirmed.

No communication further, the morning of the day before I called to confirm that all is on track and to my surprise they had “forgotten” to put my order through and I won’t be able to receive my items in time. I called for clarity and every one said “they will get back to me” but never did. I spoke to almost 4/5 people, no help.. telling me they are out of stock .. oh wrong order .. let’s check with IT.. I had to call every few hours just to get updates.

I even emailed the manager .. who never responded. It did seem like they could not care less about THEIR mistake .. and now I am left without a solution and my event is on Sunday. Because someone “forgot”. I did not even get an apology.
