"A big thank you to the whole team at bOnline from Michael Brown in sales - who patiently explained how VOIP phones work and sold us to bOnline - to the technical staff who have managed to answer every query and get us running. 1 month in using bOnline for Fibre Optic and VOIP phones and we are satisfied customers! Keep it up!"

"I did quite a lot of research first into the different products on the market, and couldn't be happier with the CircleLoop app and their customer service. It does exactly what it says on the tin. We have been using it for over three months now and I definitely recommend."
