Just received a PayPal payment today with the following message (for my May 5th shop)...
"Note from HS Brands International:
This is your payment for the shops completed. The rest of the May shops will be paid by August 15th or sooner. Sorry for the delay. Please go to www.mymysteryshop.com to view your breakdown. Thank you"
I got paid on August 11th and 12th for May shops. I never have to chase them, so I just wait patiently. The PayPal payment has arrived, and experience has taught me that they are often late.
