Renault bad correspondence service

I won't take my car to Renault Fountains for service again Because you will struggle to get hold of your service advisor should you wish to enquire about your car while it is there. It's now 15:00 and I've been calling since 12:00 and switchboard operator has just been saying. The service advisor's phone is unavailable. I asked her(the switchboard operator) to send her an email and still she hasn't responded.
