I have spent tens of thousands of dollars with Beauty Bay over the years - All orders solely for personal use.
 I was in the highest tier of their loyalty program and then .. STOP.
 Time and time and time and time again , beauty bay (they dont deserve uppercase B) summarily cancel my orders. 
Nothing strange about the orders. Normal consumer orders.
 No bulk quantities - Its personal orders / use.
 Always paid with via my linked PayPal account with the same shipping and billing address.
 Cancelled. Cancelled. Cancelled. Cancelled.
 Every time I reach out to beauty bay customer service - there is NO such thing - and ask why this is happening the ONLY response I have ever had - The few times I’ve had a response at all is a cut-and-paste insert template saying the order failed:
Security checks.
 OF WHAT?
 RE WHAT?
 WHY? 
WHAT DOES THAT MEAN?
 WHY DONT YOU WANT TO INVESTIGATE FURTHER? 
Its so particularly bizarre because I had placed dozens and dozens of orders and then - now . Im seemingly blocked.
 I have no idea why.
 There is no way of having any kind of written or spoken conversation with beauty bay - Im just ignored, discarded. 
Its not even the products or the orders that I care about - I can spend my money a thousand other ways.
 It’s the total and utter disregard and disrespect and contempt with which I am treated.
 Never knowing why I’m cancelled is so frustrating when I know they’re just normal retail consumer orders.
 No one at bb will EVER offer assistance or even look at what is causing these blocks on my profile - Something is wrong / stuck / blocked in their back end system - But all I ever get is the template “failed security checks” response.
 I know bb is WAY too big to give one excrement about me - But for the sake of a companies performance . Wouldn’t they want to understand why more than $6,000 worth of attempted orders over 3 years has “failed security checks” when the same customer has been loyal with them for more than a decade!? What if this same problem is happening with a significant number of other customers!? Is bb SO big that they are absolutely 100% fine and dandy with losing the money - and the customers who's total life spend - if there are more like me - would be hundreds of thousands of dollars !? 
What an insane business model. Just appalling.
