Sell your device and dont pay you

They sell your device and then dont pay you for the device within the very confusing 2 allotted time periods given to you. You need to think very carefully before using their services. I have sold 3 devices previously via phonetradr which were fairly good experiences with each sale getting progressively worse and now the 4th devices sale is not at all god. They do not return mails and all promises fail to come to fruitition. They need to have a wakeup call from ICASA or stop playing games and run their business as it should be run.
