My Verizon Internet Gateway device failed on Monday around 6 PM

My Verizon Internet Gateway device failed on Monday around 6 PM. I called Verizon, waited over 20 minutes for assistance, was told a new device would be sent, to expect delivery in two days. No device received at end of day three. All my mobile hotspot allowance had been used because I was using my phone to hotspot for my home business computer for three days. I went to the local store who could not provide a replacement cord for the gateway, could not refresh the mobile hotspot allowance, could not compensate me for three days without Internet, and lied by saying the device had been delivered. When I was suckered into signing up for Verizon Internet, a gateway device was provided to me by the local store, yet they somehow cannot provide replacements when the equipment fails within 2 years, or help in any other way.
