Bata India — Annual Discount coupon not received

Hi, we have four family members who are shareholders of BATA. We did not receive any discount coupon last year. This year also, only one discount coupon has been received on one member's mobile.
Is the discount coupon distribution now random or has the eligibility criteria changed?
Our family would keenly look forward to these coupons and shop for the monsoon wears from Bata.
Can you please help us to get these discount coupons? Please let me know what information is required and whom to send it.

Thanks.
