Compuscan please help me properly

I have had excellent experience with compuscan in the past but it seems this has come to an end now, Since january 2020 I have been working hard on improving my credit score and it has been fine until March since then my score has remained the same , this month for some reason it has dropped by 7 points! What for I do not know and the call center agents can't help either, I have asked for a team leader to contact me and they have promised to have one contact me but this never happens. I have also contacted the NCR and ombud but no joy there either - - what can I do
