Axis Bank — Bank not issuing sovereign gold bond certificate

Address:

Kolkata, West Bengal, 700159

I've bought sovereign gold bond on 14th july which was issued by rbi for gov of india through online axis easypay. But when i asked bank to provide me the certificate they are denying saying they don't ave any information. Then i called axis customer care phone banking they are asking me to get it touch with branch even though i said that i already asked branch but still the customer care insisted to get in touch with bank branch as they don't have information. I need help to get it resolved as i'm uncertain about my sgb investment through axis bank.
