Why do SIP keep ignoring DRT clutch problems

I ordered a DRT clutch for a PX200 elestart

The steel plates that are fitted to the DRT supplied do not fit my COSA style clutch drive spider.

The steel plates supplied are for the old type clutch, ie the hole steel is much smaller.

All I need is SIP to show how I can get the correct steel plates or which clutch drive to buy to fit the supplied plates.

 

I have sent several emails with photos , but SIP after denying I had the wrong plates are now ignoring my email.

Any help welcome
