Keerti Computer Institute — fees fraud

Address: Mumbai City, Maharashtra, 400009

I have paid rs 8000 as september month installment to arun sir of keerti institute dongri branch i agreed that amount is 8000 and handour me the reciept. And after an hour he called me and told that 1000 is less in fees but in reality i gaved him 8000 full he conuted twice. He is trying to lie and take that 1000 rs for their own use. After calling to madam of that institute she checked cc tv and accepted its their mistake. Actually that sir is trying fool me. But camera chaces everything...
Now i think keerti institute is not good for conputer studies because their teachers are lier and trying to do fraud with students... And also that have small space for computers all students are not comfortable in the class due to small space and less computers.
