Potential legal matters. Where is SADMG?

I have been under debt review with SADMG since August 2018. This will not be my first review as I previously posted a review for statements.

Now a new problem has surfaced.

I have been recieving calls from multiple attorneys requesting payment to be made as a few of my creditors have not been recieving payments since the month of March 2019. As this is of urgency I have tried making contact with SADMG for the past 3 weeks, but all their telephone lines stay busy, none of their email addresses work as every email I send keeps on bouncing back and their website no longer seems to exist.

Did the company move? Were changes made that the clients were not made aware of, I would expect such a company would advise their clients of any such changes?

I am looking at potential legal matters and I have no idea how to proceed regarding this as the services I am paying for arent currently available to me.

HELP!!
