"The IMhrplus support has been invaluable to us highlighted by the fact that we have had the service for nine years now. The service is great as there is always someone there, you never feel as though you have to chase anyone. I have built a great relationship with IM, I go to all the events and travel an hour out of my way; just so that I can get the service I need and want." - Premex Services
