Here at HYLA Mobile, an Assurant company, we offer a white-labeled customer service function for our trade-in services. In other words, if a customer contacts one of our customers (carrier, retailer, OEM) with a question about the phone they just traded in, that question gets seamlessly shunted in our direction.
Our support is offered via phone, chat, and email, and many if not most of our support requests are received online. In fact, the number of support queries we receive via the internet is very large and continues to grow, which could lead to a problem with scale.
