Hello!! I have a Macbook Pro retina 13"(mid 2014) (model:A1502). Yesterday I took my mac to the technical service because the mouse is not working well, and I did'nt know if the problem was software or the trackpad.

They say it's the trackpad, but they should change the whole topcase, and it would cost me almost $ 700 to repair. They say that in this model can not be changed only the trackpad!!! From what I'm seeing here they did not tell me the truth.

How or where can I get a trackpad of this model to solve my problem? Amazon? How do I look for it and how much can it cost? Thanks a lot!!
