I ordered the router on Sunday but still did not receive it yet tomorrow its 5 days as they promised but there is no sms as they promised that the couriers will contact me with an sms. Even a sales agent that help me did not follw up if I've received it or not, she is quite. She was good and patient when she wanted the sale, she got a sale but never followed up with me
