Faulty Huawei LTE device

Faulty LTE device delivered to me. Mobile Talk customer Care centre officials are not progressing my complaint effectively - no service after 8 days of waiting. Michelle McKenzie simply replies that the matter has been escalated but that she can't provide me with any contact details of any person with authority to attend to my request. She also says that there is no way that I can personally attend to the problem and simply have to wait patiently until they attend to the problem. This is the worst customer relations ever! I will not recommend any form of service through Mobile Talk to anyone! Be warned of very poor service delivery by Mobile Talk!!!
