Axis Bank — benetton bag offer

Address:

Hyderabad, Andhra Pradesh, 500049

Two months i got a mail saying that if i make fixed deposit 25000 rs in my saving account from 31st march to 10 april i will get a benetton bag.
When i contacted one of axis bank executive he said within 2months i will get a coupon for the same. Now its more than 3 months and there is no coupon or no communication from their side.
I seek a proper clarification and exact date till when i can receive that text so that i can take my benetton bag.
I have sent 20 mail's to customer. [protected]@axisbank.com,
But i have not received any proper feedback from them.
