Door and shutters - K par K? Or others in Charente-Maritime?

We want to fit aluminium doors, shutters and the gate on out property near Jonzac. We’ve been talking to a company called K par K in Saintes who seem to have what we need but are a bit unresponsive to emails which is making us a bit concerned.

Has anyone had any experience with them or can recommend reliable companies in the Charente-Maritime?

All comments much appreciated!
