If they are a Playtech I tell them that I am not happy with Playtech’s role in providing player support and I’ll only represent casinos with a perfect history on Casinomeister (they rarely have!).
If they are an RTG I tell them that I am not happy with RTG’s role in providing player support and I’ll only represent casinos with a perfect history on Casinomeister (they rarely have!).
No-one else bugs me 
Nor do the Playtech’s anymore
