Products are great if you can get them. I'm a retail store that has the option to sell focus products. I will no longer suggest them based on their customer service.
Here is my email I've been trying to get my materials.

"We changed this on the 17th, due to you didnt have stock of the lower cost one. We were not informed that item was on backorder. When I discovered we found a solution and changed the PO to one that was in stock it was still never delivered till I had to follow up again on where it is. This makes you guys the only the poor customer service list. Less likely.to want to repeat business when it feels like as a customer I don't care. I would.never treat my customers this way."
