Technically you don't always have an automatic right to cancel without penalty just because the terms change, but it really depends on where you live and what your original contract says. In many Latin American countries, if the platform substantially modifies the service you signed up for (like removing features or significantly raising the price), you have the right to cancel without extra costs, especially if that change affects the value you're getting. Your best bet is to carefully review the terms you accepted at the beginning, check what consumer protection laws apply in your country, and if nothing's clear, contact customer service directly with a written message explaining that the change reduces what you paid for; a lot of times they'll let you go without drama to avoid complications.
