Two months and a half ago I requested the gas, they did not supply me because they discharged another person with my address and until they do not fix it they do not give me gas, I do not have a meter or gas, I live on the floor my two children of seven months and my partner, I have written them e-mail and they ignore me, does anyone know if legal action can be taken? Greetings,
