Try a New Charger:

If it is charing from an external device, then use a new charger:

• Power & Cables - Mac Accessories - Apple - Select "Mac Compatibility" on the left
• Find the Right Power Adapter and Cable for your Mac Notebook - Apple Support

A Few Links to Refer to Power:

• If your Mac doesn't Turn On - Apple Support

• How to Turn your Mac On or Off - Apple Support

"I bought this brand new macbook pro about 2 months ago so there can't be an issue with the power adapter or with the charging cable."

Warranty Coverage:

Well it's a thought. And if it is a new purchase, Apple would likely cover it under warranty, if found to be a faulty device. You have a one-year, out-of-the-box, limited-warranty with it. So, contact Apple, seeing what your options are for hardware coverage.

Contact Apple Support:

• Contact Us - Choose Locations
• U.S.A. (800)MY-APPLE
• Proceed from there as necessary

Note: Phone calls are taking a bit to go through at the moment, due to lots of calls. With the Coronavirus Pandemic, many are at home at the moment, with much time on their hands to contact Apple. So, just stay on the line, and you will get through :)
