I am not familiar with this particular company, but I was a buyer back in the day and the one thing that was out of our control were the manufacturing companies,
We would go to market and find fabulous items, order them and the companies would promise them.. We would plan out catalogs, mail outs, etc..based on these buys months ahead of time . people would begin placing their orders and the merchandise might never come.. or would be running late.. Then the companies were not able to fulfill the orders. Drove me insane!
Sometimes the company had run out of the fabrics, if imported the shipments took too long, or were lost and hopelessly late. Or the company went bankrupt.. Same with small mom and pop manufacturing..
I assume it is still the same.. I do hope this company is prompt about crediting you. That was always a priority, of course we never charged a client until the merchandise came in, but I hated disappointing clients about these items.
