Worst service

I submitted a 3rd party claim to momentum, the following day my claim was forward to someone else and I was cc’d in the email. Not long thereafter I received a call from someone telling me they have been appointed by Momentum to investigate the claim and that they need to assess my car. I just called Momentum 7 working days later and I’m told no one has been appointed. The person dealing with the claim just told me they will follow up and dropped my call. The people has been very unprofessional and the service is not what I expected from Momentum, the people are very unhelpful. I need someone to urgently advise me what is going on.
