Help...need to get a message to our tenant in St Nicholas du Pelem urgently and need someone to offer a service like this regularly

Is there anyone in St Nicholas du Pelem who would be prepared to pop a note to our tenant telling her we have been trying to find a roofer to look at the house but no success so far? Post will take too long and she does not do texts or emails. Have left messages with her by phone through a French friend here in London but she is not picking them up or returning calls. It would be helpful to have someone we could use to liaise with her on a regular basis re issues - not sure if people offer that kind of service. She does not speak any English.
