ShippingSign24HService.vip review: 5 makeup bags

I never received my order and have been sent multiple messages indicating it was was returned to post office with the following explanation -

Thanks for reaching out to us. We are so sorry for this case.
As we checked, your parcel has been returned by your local post office
What’s more, this parcel will not be returned to our original warehouse, which means we can not receive the parcel neither. If you still want the product, we can resend your order, but this time we need to charge some money for our loss of the product and the first shipping fee. Waiting for your choice. Thanks for your understanding!

Yours sincerely,
Customer Service Team
I have emailed the company numerous times asking for my refund as the parcel was never received with no resolve.
