  In this work we study the Quasi Normal Modes(QNMs) under massless scalar
perturbations and the thermodynamics of linearly charged BTZ black holes in
massive gravity in the (Anti)de Sitter((A)dS) space time. It is found that the
behavior of QNMs changes with the massive parameter and also with the charge of
the black hole. The thermodynamics of such black holes in the (A)dS space time
is also analyzed in detail. The behavior of specific heat with temperature for
such black holes gives an indication of a phase transition that depends on the
massive parameter and also on the charge of the black hole.
