Can anyone give a reference for DDD / DFSD Production?

Hi Girls/guys

Has anyone shot for DDD Production (name the email came from with the addy of )
They have contacted me about doing a shoot when they are next in the UK.

I have asked for references but as usual with foreign companies, they completely ignored or maybe mis-understood my request, by just replying with a watsapp number and saying they want to get it sorted quickly - this sets off alarm bells for me but I regularly turn down work that I don't think is legit to then find out afterwards that someone I know have worked for them and they was great it was just a language communication problem.

So I just thought I would see if any of you lovely Models/Performers on here have worked for and can vouch for them otherwise they'll be getting a no thanks from me.
