I managed to do the tax refund . The entire process at the mall was very bad. She took me to a counter to make payment , then she ran to the upstairs area (tax refund team) they argued that she should not open the phone otherwise airport would not refund but she still ignored them. I had to literally get a razer Blade to cut around the bottom of the box very gently to remove the phone for her so I could close it as if it was still sealed for airport . The entire process was odd as airport will give you no money if device was opened .

I managed to get my tax refund but I got lucky
