They forgot to process the order!

They forgot to process the order!
They have a product title, "Screen Protector", and when the order arrives, the screen is not the protection for it!
I want to make a return, it is very difficult for me to answer and I am told to fill in the return form and go with it to the courier and also with my money to make the return. Even today I have not received the details necessary for the return as he told me.
2 stars for price and quality, their services leave much to be desired in return, they can be considerably improved.
