Terrible Service and No Assistance

I placed an order for a Wifi router on the 26th of November and 12 days later I still have not received it. It was supposed to be delivered within 3 to 5 business days. I called them everyday last week and they advised that there's nothing they can do to assist me yet I paid for the Wifi package and router. Such bad service! I haven't heard anything back from them yet and when I ask for management to call me they don't. They also not willing to provide me with answers as to why there's a delay with my delivery.
