Muthoot — about misleading in interest%

Address: Kanakiya mira road thane, 401107

I have taken a gold loan from muthoot finance, they told me i[censored] that under 50000/- loan will provide u 1% int. So. I have take schemc. My due date was 27 april and i paid on 29 may. Thay charge me double the amt. About 1.7% per month. When i asked them y, they said i[censored] don't pay on same day then ur%will charge for whole month. When i said u haven't told me this at the time of taking the loan that ur% will change i[censored] don't pay before due date. They told me it is written on the paper. I just want to say it is misleading to the client, at the time of taking the loan they should give each and evry details porperly. Very reducules... Stop giving add of 1 % int. Stop making fool to the people.
