Waiting for a call back from a supervisor

I am currently waiting for a call back. It has been several days since I was told that a supervisor would contact me and no one has contacted me. I was clearly told by Comcast, when I signed up for Comcast business services, under a 2 yr contract, that I would NOT be penalized if my store went out of business and I no longer needed the service. As a new business owner, I wanted to be clear on that! Unfortunately, amidst current worldwide events, my small, local, thrift store has closed. Comcast is trying to penalize me $1,300, after I was told that I would NOT be penalized if my reason for disconnecting service was due to going out of business. Recorded phone calls can verify that! I am trusting that Comcast will do the right thing on their own, without waiting for a presidential order forcing large corporations to forgive such penalities against small businesses that have closed during this time.
