MoneyTap — Need to Foreclose my loan. But, no response from them..

Hi.. I have taken a loan from MoneyTap app, for two years. Currently, one year have been passed. Now I need to Foreclose my loan. But. There is no response from them yet. Because of their irresponsible behaviour, it seems I may need to pay interest to them for next one more year. Interest for one year itself coming around 28K extra. It is such a cheap tactic of cheating. Indian govt should never allow this kind of company. I'm wondering how RBI allowed them. Someone please help me to save my money from them..
