I have returned my PPM in March, it was successfully received at Hong Kong delivery address (notified via tracking number). Since then no one has contacted me and this is a bit upsetting. I believe in the product, but either replace it or return my money. At least an email from the company stating the PPM has been received and we are verifying what is wrong and will get back to you shortly. It been two months and no word. What do I do???
