SIHI Dropshipping Fulfillment

STAY AWAY!!! STAY AWAY!!! STAY AWAY!!! STAY AWAY!!! STAY AWAY!!! STAY AWAY!!! STAY AWAY!!! STAY AWAY!!! STAY AWAY!!! STAY AWAY!!!
The WORST fullfillment company I've ever seen. I'd like to give negative stars if there's option, because they are absolutely fraud.
When you try to add products to your store from their website, you have to wait for manual processing to add product details before you can add them to your store. Meanwhile, inventory information is completely opaque.
I saw some comments pointing that they ship very slowly, and some orders weren't even fulfilled. Fortunately, due to the complexity of their website, I ultimately didn't choose to ship through their company.
Afterwards, I asked customer service to delete my account and clear all my data. Their representatives verbally promised to do so, but they would NEVER delete that account. All my information remains in their backend, and I keep receiving their marketing messages, which I could not even unsubscribe!
When I look at their reviews, I genuinely question how many of those positive reviews are even real, because the service I have experienced is nothing like what those reviews claim.
This company is not only completely dishonest, but also extremely annoying! I will never recommend them to anyone. Just do everything you can to STAY AWAY from SIHI Dropshipping.
