Totoodo.com — Not returning my Macbook

Address:

Neeladri Road, Electronics city Phase 1, Bangalore 560100

I have given my macbook to fix a issue which TooTodo fix few months ago...I have given to Neeladri road, electronics city, bangalore branch.. Initially they told that they need to replace battery to fix the earlier problem so they charge that ..When I claim that I didnt gave permission to change the battery they got furious
For last 1 month they are not returning the my macbook. 2 weeks ago somelady named Jyoti told me she will send next day .. since then almost everyday I am goimg to the shop but they are not giving and lady is telling me next day each time I asked her.. Lady's tone was also threatening. She is telling she is from head office and without her nothing will move.
I never faced this kind of bad behaviour from anyone.. I have all the chat history also.
I want it back quickly. Please help.
