I learned the hard way to always have at least two ways people can buy things from you. Never bet your business on another business that uses algorithms to arbitrarily disconnect yours and algorithms to respond to customer service inquiries.
You cut yourself from a lot of opportunities that way.
Don't say you weren't warned :-)
This is how modern life works: almost everybody's life circumstances are dependent on large institutions, which can screw you any given moment, except if you chose to live in jungles.
Doing business is taking risks, and one has to be ready to lose.
