Apple India — activation lock

I called the customer service on june 27 2018 and they told me that they will unlock the phone within 3 days and on july 4 2018 when i call them again, they are telling me to send the files again. This happens only in india if it was us they il do within 5 minutes. Bad customer service they won't even call back and they can't even help me with the stuff they doing

I need to unlock the activation lock of my phone. It has been 1 week and they can't do anything to resolve it
