We have been using Crystaline for many years now. Their service is very professional and they are always available when we call or leave support tickets.
We currently use them for all our mobile phone contracts/land lines and leased lines and they also manage the telephone system that they installed on premise for us.
I would highly recommend Crystaline as their service/products are excellent and they always manage to give us the best deals when renewing our lines.

I've been working with Crystaline for around 3 years now. I've always found their service professional, helpful and just as importantly, readily available when needed.
Their tariff suggestions on our recent renewal have demonstrated a considerable saving to my company, which is always welcomed!
I have no trouble in recommending their services to anyone looking for mobile, landline, or any aspect of voice communications.
