Nestaway Technologies — Asking to pay extra amount

Address:

A3-402,SP RESIDENCY, SP RESIDENCY ,SP INFOCITY

I have moved to nestaway on Dec 20th and while moving they assured one more girl is gonna move in there along with me as there was nobody else staying at house. The house was whole dirty when i visited before my move in and they assured everything will be cleaned. But it was same when I moved and the other girl requested for deep cleaning and also for repairing her toilet flush but she didn't stay seeing home condition and moved out. I requested them to repair the fridge, unblock the sink and to repair toilet flush of mine which was non working. They came to repair the fridge exactly after a month and did some cleaning for name sake.
I continually requested them to unblock the sink as I was not able to use kitchen so was having food from outside. I tried to contact multiple times when foul smell started coming out of sink and it was whole covered with insects and worms. Finally I had to call a man from outside and they charged around 1000rs from me for that.
And now the nestaway people had added some bill to my account saying that it's for repairing the fridge, repairing toilets flush of a different room and deep cleaning and few more things which I even don't know when they repaired. My toilet flush is not working from the time I came here and they are not even ready to repair it. It's me alone living here and now all bills which IAM not responsible for has came on my shoulders.
Why should I pay for things which I am not responsible for and now they are telling me to pay the whole bill. Now it's like I came here to pay for repairing nestaway things. The amount they are asking me to pay is around Rs.2800 and also I paid 1000 to get that sink unblocked.
Now I have decided to move out of this house as I can't bear anything more like this kind of rubbish acts from them.
They are gonna get the whole amount from my security deposit.
