Kidzee School — truth kidzee sector 4 udaipur branch

Our son (Vansh jain) went to kidzee playgroup school four days.in four days, first day he learned “ek chatta padega” and diaper was not changed even once due to which he got rashes. Whenever i went to school he was with baiji.
We have given form and cheque on day one because of kidzee reputation, our cheque was returned as bank informed there is mistake in word and numbers. We informed to school about cheque and said it very clear that he will not continue school as he was very afraid of the environment. After two months school again represented the same cheque and it got cleared. When we asked why you did this then the director said it was bank mistake and we are not aware of this. They took 15 days to revert since they follow old method like checking voucher and getting physical statement. Finally they said we will not return the fee since your son admission is done.
My simple question is how it is done … no dress, no bag, no student id allotted and there is no message or information in two months and we informed he is not going to come. We have been charged one whole year fees for no admission. Are there any ethics that the school has? If no, no one should even think of sending kids to such an un-ethical school and director.
