Hola, Elisa, you appear to have it right. You could say, "they turned off the electricity because I had not paid the bill" or "they cut off the electricity ... " or "they are threatening to turn off the electricity ..." (in place of "electricity" you can put "water" or "telephone service"). People use the term "outage" when there is a natural disaster or there is not enough electricity for everyone. Then you could say there is an "electricity outage in my neighborhood".
