Anandabazar Patrika — not receiving my subscription coupon

Address:

Kolkata, West Bengal

I am a existing subscriber of anandabazar patrika (Daily bengali news paper), i have renewed my subscription last march, 2018 which was already started from april, 2018 for 6 months subscription. But till date that subscription coupon will not sent to me, i repeatedly concerned to customer care helpline about this matter but they are unable to solve the problem. Sorry to say; i think they are (Help desk personnel) worthless.
So, i request you (Higher authority of the concern department) please do the solve for the above matter as soon as possible. Vendor person knocked my door daily for subscription coupon.
