Bought Quietas and this product did not work. Tried calling to return, the phone system was down. Tried for several days. Sent an email. No response. Call a couple of days ago. I was on hold for an hour and then the phone system hung up on me. Sent another email stating I was returning the product. Wanted a total refund. This is a scam. They are so ready to take your money but will not even call you back for a return.
