“Efficient and helpful”

We transitioned over from Comcast Voice Edge (don't recommend). The transition process to teams phone was relatively smooth and they helped guide us through the entire process. Their support seems to be helpful and responds quickly. We've only been using them for a month or so, but our situation is already better than when we had Comcast as our provider.
