¿Por qué dejas que te roben?

Why don't you rebel every time a company breaks what was agreed, charges you abusive amounts or refuses to give you the attention you deserve? Electricity, gas, telecommunications companies, insurance companies, airlines, banks... commit all kinds of irregularities with almost absolute impunity. How much abuse can you put up with without lifting a finger to change things? Why don't you use the power you have more often? This is a guide to deal with toxic relationships with companies that seduce you with bad arts, with promises that they only keep at the beginning of the relationship -or that they never even keep- and that really only want you for your money.
