Rapid charger not working. What to do?

Recently my wall charger (rapid charger) quit working. I'm just barely inside my one year of ownership. I called Google, and they reluctantly sent me a charger for free. Just got the new one today (very nice btw; must go with the Pixel). I plugged it in the wall and phone still didn't charge, at all. While waiting for a new one, I have been charging with the USB-C to USB-A port into my computer. Didn't fast charge but it sufficed.

So, now I'm thinking it may be the phone itself. A short possibly? I never had an issue with a charger before so I'm not sure what is the best solution. What do you guys think---the phone or another bad charger??
