NPDA/ IPDA so Disappointing!!!

I have signed up for debt review in 2017 through NPDA, I have never skipped a payment, never paid late or less than the amount agreed to. Recently my statements changed from NPDA to IPDA and nobody called or emailed to explain why the change. Anyway I never had a problem with that until MDP started bursting my phone saying I have an occount which is now 5 months in areas, I called IPDA and all I could get was "we will investigate", over a month later still no feedback on the Matti, no response to emails and I no longer get monthly statements like NPDA used to send, since IPDA I always have to reguest for my statement every month, I can't talk to my debt counselor because he apparently doesn't deal with clients directly and only Queries Administrator can assist, then who's exactly my counselor??? Right now I'm stuck after a million calls between NPDA /IPDA/ MBD and the Service provider. It's so frustrating especially if I have done my part which was to honor my payments as instructed, but experiencing such horrible service is not fair.
