I can exercise at home during the holiday, but I didn't expect it to arrive in ten days. Looking forward to the stars, looking forward to the moon, looking forward to the machine, the treadmill was finally moved upstairs, and after the after-sales installation, the treadmill was plugged in and broke down. The installer is speechless! After two hours of communication between the installation master and the after-sales service, there is still no way to start it. Not to mention my mood at that time. The fitness equipment manufacturer called me to ask why the visa was refused. Didn't your after-sales service reflect the problem? Didn't the company use the management system? I'd like to ask if our treadmill has not been tested before leaving the factory. Where did you get the certificate on the treadmill? Won't you try it when you send it?
