Hello, as everyone knows we received many more orders than we could handle in March. All of the orders were shipped out and have now been delivered. We are extremely sorry for the delay and have made improvements in our processes so that this will not happen again. We hope that you will consider us again in the future.
Best Regards,
Sarah

I just placed an order and specifically used PayPal. PayPal will contact them for you and give them a specific amount of time to supply a tracking number if it doesn't show as being arrived to you within a certain amount of time you will get a refund from PayPal. PayPal always has your back.

I believe their ads say that you should get it in 10 business days. So, if a significant amount of time has passed you should start your complaint because afterwords you have to escalate it. The sooner the better to get started.
