IDT Global vs CircleLoop

We started working with IDT in 2016. They tout serving over 32 billion minutes annually and 4 route divisions to choose from. The route divisions are irrelevant however, here I will explain why: The level of service/quality you *actually* receive depends on how greedy your Account Manager is, and the genie behind the curtain that changes up the routes to accommodate their desired margins. The end result of course is route instability and frequent calls to your support desk from angry customers reporting issues ranging from False Answer Service to calls not completing to legitimate destinations and wondering why they are paying for Platinum service only to receive problems typically associated with Silver-grade routes. With IDT we'd literally pass weeks at a time without issues, and suddenly a range of issues with many different destinations arise at the same time. We submit the ticket and the issue would eventually be resolved, but only after waiting > 24 hours for a response. In the IDT Express portal you are able to select which routing division, but in the end IDT simply does not honor your selection, and will route your traffic over the routes they choose behind the scene. It's really a pointless set up they offer. Go with Tata, NTT or BT if your customers' satisfaction is paramount.
