I've been with Yay for over a year now and I'm impressed with their services. Their prices are reasonable, and they offer flexibility that benefits my business. The online platform is easy to use, and I can opt to make calls on my desktop, my mobile phone, or my Grandstream desk phone. Most of all, I'm impressed with their customer service! Dom was knowledgeable, helpful, assuring and patient. He helped me navigate through all the things I needed to change and the customer experience was pleasant! I a a happy customer and I highly recommend using Yay...it's a real "yay!!!", I have to say when Dom sorted everything for me.
