Blackmailed on IG

Last Friday I was scammed and am now being blackmailed I paid some money( more than I should’ve). I found this thread and it has helped reassure me that nothing will happen. They have been in contact every few days and are now using a different email address to text me. I told them I could pay more at the end of the month. I have replied a couple of times. Should I just ignore them from now on? I would go the police but feel that they wouldn’t do much about it. I’m not going to pay anymore but I’m scared that they may send them if I ignore them or don’t pay. I have reported the accounts they used and one of them has been removed but they can still use other accounts to share them.

I haven’t told anyone about this as I’m not sure how they’d react.
