Bajaj Finserv — application status of emi card

Address:

VPO-Kokri Kalan (Patti-Usang), Moga, Punjab, 142001

I had applied for a emi card online and already paid fees worth rs. 500/- approx.in sep/oct 2018. I received message about its acceptance and was congrats. My purchase limit was informed about rs. 75, 000/- but unfortunately, in fact my purpose was to buy an ac on emi for my home during this summer. But now when i visited to a bajajfinserv store for buying an ac, my status is shown as 'block'. Please inform me about its reason. I have not yet made any purchase on the said card.
