After paying my first instalment, I had high hopes

After paying my first instalment, I had high hopes. I was added to the company's What's app group together with their staff members supposed to guide me through the debt review clearance process. I missed on a payment but got in touch with them a few months later to make payments to catch up. I never got a response even today. I tried to call their landline to no avail. I realized that certain staffers we exiting the what's app group. I realized that the company was dead. I think they ****med clients.
