Skoda India — ac trouble in my 2014 skoda rapid

Address:

Mumbai City, Maharashtra, 400049

AC in my 2014 SKODA RAPID keep turning on and and off continuously
Approximately 3-4 times in a minute

I have got it checked at the authorised service center they have diagonised a faulty compressor.
when I got it checked from an outside AC reapir specialist, they performed a scan of the vehicle and have diagonised an ECM problem.

I fail to understand what is the real fault. Can anyone help or guide me to a good source who can solve this issue in the right and cost effective manner as i dont want to use this car for more than 6-8months
