PaySense — bank loan harassment - calls the contacts in my phone

Address:

Mumbai City, Maharashtra, 560084

Can any loan app access their phone contacts and media stored on the phone. They are calling the contacts in my phone for emi default. I had installed the app and gave permission to access my phone. Does access mean they will be able to view the number or can call them? And also i have uninstalled the app now, does that mean they don't have the permission now? I have told them i am unable to pay my emi due to unemployment, however they stil keep harassing me and contact my previous company colleagues.. They are mentally harassing me and defaming me.. I m thinking of filing a defamation lawsuit against them. Please help. The people calling doesn't have courtesy and have zero communication skills and speak bad words.
