Umm, I am in the same boat. Got a recent decent hike in my salary. Hence applied for LE and card variant upgrade to DCB. Got a reply in ten days, That my limit is increased. I checked it on my app, The same limit. Then pinged them again, They got angry and told me that it is already enhanced...
I had actually applied for manual Limit enhancement, CC is confirming that it is enhanced. But my netbanking page is not reflecting anything and there is no quantum of enhancement in the mail. Any ideas?
