I bought from an online site named thenanodesigns and myself and many others have not received any of the items that we have paid for. This is what happens, there is a number which you can call to get in contact with them but its a dead line. There is is an email address which is another option to get in contact with them. They fail at even replying even after 50 times. There is an inbox suggestion in which you will be ignored. After getting very frustrated you start to write on their facebook advertisements and then they will block you from it so there is no way of contact. They take your money and run. Do not buy from them, they are fraudulent. Disgusting and fraudulent. I have spoken to many others who are experiencing the same. Awful.
