Which are the top colleges in Mumbai for digital marketing?

Hello! As of now, there is no specific college dedicated anywhere to teach Digital Marketing. You can pursue online courses from Udemy, Coursera, edX, etc. To get a good understanding about it. Moreover, these courses are available at affordable prices especially on Udemy.

Rather then looking for Colleges in Digital Marketing, I would recommend you to do various certificate courses on digital marketing online from Google, Digital Vidya, Udemy (Presently, they are giving huge offers due to republic day) coursera, Udacity, etc. and look for colleges in Marketing.
