Tanishq — Employee's Discount

At Tanishq showroom Jamshedpur, Jharkhand on 18.09.22, when I asked for employee's discount, they asked for a mail giving such information & documents, accordingly emoyee sent the desired mail to showrooms mail id. After getting mail, personal at payment counter asked for another mail in other formet. Why they didn't tell about this formet in the first time? They couldn't reply anything.
This was sheer annoyance & wastage of time.
I did purchase but without employee's discount.
This has happened earlier occasions too, in the same showroom.
Emlyees at this showroom are all most confused person killing customers valuable time.
