DCB DCB limit enhancement?

[urboss]

So, when I upgraded to DCB FYF 1.5 years back, they increased my CL to 7.5L, but since then there has not been any LE offers. I tried 2-3 times mailing and escalating till PNO at some months interval, but they always declined. Although in this period, I did get TATA Neu infinity as LTF but again with shared limit of 7.5L
My salary has also increased 20% since then with monthly net salary of around 2.5L and in last 6 months I have spent around 4L on DCB and 1L in tata neu. Last month i tried again and provided them all the docs like salary slip, bank statement as my Feb & March sal was more due to some one time payouts- but same reply. Denying any LE citing internal policies.

I don't know how, but my 2 other CC (IDFC & ICICI) limit is also 7.5L, but the usage is pretty low there so never expected a LE offer there. Is there some formula with which they derive the CL value?

I just want 1L increase in the CL. Any suggestions?

Some folks have theory that if you have 2 or more cards you probably won't get LE.

yep, I read this thing at different places, hence this doubt in my mind. Since the limit is shared, the cumulative expenses should be counted for all calculation logics, isn't it...
