I use USA paypal, :D USA supplier info, not Vietnam. Are you sure they will make call to suppliers? Can i use ⊗⊗⊗⊗ suppliers? Because i use "drop shipper"
It is a distinct possibility. I read a post on here where someone gave a number they had access to as their supplier contact number and PayPal did indeed phone.
Can you not give Paypal your drop shippers contact details and notify them that they might get a call?
