Urban Company — failed to refund my money which was committed earlier

Address:	Kolkata, West Bengal, 700056
Website:	Urbanclap

My ac servicing was done by urban clap technician.. He filled d gas n took 3300 from me.. But within a week my refrigerator stopped working again.. Finally it was repaired by godrej itself which cost 5700. Moreover i came to know that urbanclap's professional had damaged various parts of my refrigerator while repairing and i was assured by them that i ll get back 3000 as refund after submitting documents from godrej but later they denied to refund... Please help n take necessary action against urban clap for cheating customers
