How to compare two lines in a csv file using shell script?

I have a file lets say input.csv having two columns like-
Code:
Name,Mobile No
A,111
B,222
A,333
A,123
B,213

I would like to find result in a new file lets say output.csv as-
Code:
Name,Mobile No
A,111
B,222

means short the file on the basis of first column and first value corresponding to the unique one of first column from second one.

Any help should be highly appreciated..... Plz help me I m a new in shell
