Doubt

Dear Sir, I have recently started tuition classes in our house and the house is rented. I had orally taken the permission of the association secretary, but after 2 months the associations are having their meetings and discussing among themselves in order to ask me to stop conducting tuition. I am ready to take written permission, but their basic requirement is to make me stop the tuition. I am really confused unable to have peaceful sleep, its easy to stop today, but my real worry is, is it really necessary for me to stop it for their objection OR I would like to know if it is not commercial activity, how would I convince them, since I have already taken into consent the nearest neighbors and they really do not have any objection. I have taken all the measures to ensure that my classes are not disturbing anybody inside apartment. It is all about my right, just because I am a woman they cannot deprive me of my right and take out from my hands my hand the basic opportunity to earn money along with my kid. Awaiting for your reply.
