LT Online Store — Did not get Hp printer cartridge HP 818 yet

I have ordered an HP Ink cartridge 818 for my printer from LT store online https://ltonlinestore.com/ . but it is a fake site they are neither picking up my call nor they are replying to my mails. I have requested for a refund by sending a mail to them but they are not responding at all.
They have taken my money but they are not doing anything with my order.
Its already been so long. I have not got any detail from LT online. They are behaving as if they all are dead.
