Bajaj Finserv — Pestering phone calls about loan

My phone number is [protected], I have purchased a fridge last year with help of Bajaj finance and have completed the payment without any problem, but after that everyday I'm getting 5 or more phone calls nagging me with loan offers, after politely rejecting the offer many times and asking the officials to not call me because I'm not interested for as long as I can remember, im being pushed to the breaking point. For the last time I don't want loan, stop calling me.. If the get any more calls I'll move to consumer court. I have all the call list. I hope this will put an end to my suffering.. Thank you.
