Dividends paid to stockbroker a/c even though stock is supposed to be held in crest

[MfS]

I have some shares which are supposed to be held in crest through Sharewatch but the dividends are paid directly into my sharewatch account and I receive no dividend statement from the stocks involved, even though I have other shares with sharewatch whose dividends statements I do receive.

Sharewatch assure me that the stocks are held in crest.

Is there any way to check without going through Sharewatch what my crest holdings are ?

Is there any way to check the compaines involved to see if I am listed on their shareholders register ?

I want to ensure that these shares are held in Crest and not a nominee account
