Loan Calls

I applied for a loan of 5L on iMobile Pay, got a pre-approved limit, slightly lower than that so I left the process.

-> Got a call from icici (from the company number) regarding completing the application, quoted the amount that I applied for (5L) I said I had a higher requirement but then eligibility didn't match so I informed them next month maybe.

-> For the rest of my day I got calls from HDFC, BAJAJ, AXIS, IDFC, INDUSIND asking about the requirement for 5L and trying to provide loan.

My point is at what point did my Requirement for 5L get leaked?? I applied on ICICI Mobile app. Would've been acceptable if I had raised a request on Paisabazar or somewhere else. Completely frustrated yesterday with the number of calls I received yesterday.

P.S: I counted, Total 30 calls from different banks yesterday and all specifying the 5L Amount.
