My experience with Dappz was similar. I purchased a part for my Samsung washing machine. The web site showed several in stock. I placed my order and paid through PayPal. I was told that my order would arrive on 12/22/16. I received nothing.
On 12/23/2016 I received a refund notification from PayPal. I have yet to receive communication from Dappz regarding the order. I went to the web-site to look it up but it says there is no record of past orders. I have an order number, confirmation of my order, and received a refund. Hmm?
While on the website, I noticed that PayPal is no longer listed as a payment option. PayPal probably dropped them due to their shady shenanigans. I placed a new order with a reputable company. Unfortunately, me and my kids will spend Christmas at the laundry mat so that we have clean clothes for work and school.
