Marianna PooleBeckett Investment Management Group have been working with Ocean for a long time and are very happy with their services. We are really pleased with a recent softphone system installation in our offices. All throughout the process we had their full attention and they made sure that all our expectations and needs were met. A pleasure to deal with!
