Bajaj Finance — daily calls regarding loans

I am a person ho have used bajaj finserv and like have a card too.. However i font want anybody to call and ask every day 5 to 6 times asking whether i need loan.. Also when telling not to call, they its automatically dialled and being rude.. Also when i called bajaj cx care they cut the call after arguing. Worst customer service guys!! So embarassing that i used your ptoduct. I got a call from the following number -[protected]. My number is in donot disturb list and if i get any further calls i will have to report this.. I want them to be fixed right away.
