Bajaj Finserv — bought a mobile phone on emi

Address:

Mumbai City, Maharashtra

after getting the phone on the emi card, after paying a downpayment ideally the emi should start after 2 month. before the due there was no calls...but today since 5 hours i am gettinf 15 calls asking me to make the payment... where and for what these people are harassing since morning even though i informed i will do it till eve because i am attending a marraige.. still the same continously... was it not the finance companys responsiblity to call prior and inform about the glitches happen during the time of processing the loan amount...
