No delivery- New balance online

I’ve placed an online order and paid on the 29th November( Black Friday) by the 10th December I had received no delivery I emailed the customer service and advised there was no stock which it didn’t say on the app. I was given 40% discount on my next online order I then pl Ed another order on the 14th December they refunded me for the last order and I paid for the 2nd order I advised Kay-Lynn the consultant that I needed this item before Christmas she confirmed that there is stock available in the size that I wanted and she will let me know the delivery status. On the 24th December still no delivery and she said that there’s an issue at the warehouse then no reply back after 3 emails wanting this order. It’s disgusting service from new balance, what is the point purchasing online and they don’t deliver?
