“I strongly believe in giving praise when it is due and therefore I would like to extend my gratitude to you and your team for your impeccable services and assistance during this past telecoms crisis. I have not come across another group with so much experience and knowledge in IP telecoms coupled with the tenacity to get our systems up and running in such a short time frame.”
