Royaloak Furniture — Pushing delivery dates from last 30 days

We have placed an order on 03 January and to day is 27th January. They said all products would be delivered within 7 business days but two items not delivered as of today. They said the following reasons every time we contact-
1. Vehicle met with an accident
2. Systems are down
3. Items out of stock, items were available at the time of taking orders
4. Sales person and store manager don’t pick up our calls most of the times
5. Call center people are helpless not useful at all

I would not recommend RoyalOaks to anyone after going through the painful experience. Help me close the issue if it’s possible.
