During the modernization of our network equipment, the number of calls from subscribers increased several times, and our own support line stopped coping. Subscribers waited for hours for an answer, which caused a wave of negativity on local forums and a drop in loyalty. We urgently needed to strengthen the team with professionals from outside. We have signed an agreement with the call center outsourcing company, which promptly allocated a trained group of operators to receive incoming calls. They did an excellent job of conducting the primary technical diagnostics of the equipment on the user side and reduced the burden on our line engineers. Thanks to this step, we were able to stabilize the situation on the network and regain the trust of our subscribers.
