Loan Quest sa / Lifestyle legal

From other reviews ive read about this company its clear i aint the only person getting these threats from Lifestyle Legal. Who are these people? I got my first email (FINAL DEMAND) from Lifestyle legal on 04th October and continuously have been receiving threats from these people for payment. If you send an enquiry email to them all you get is a ticket number and then another final demand.

Is this the legal way to collect money for a loan process that never happened? And are they allowed to demand money in this manner?

Ive sent more than one enquiry to these people with no response besides a final demand i keep receiving.

What can a person do regarding this?
