Slicepay — No customer support

Who do I contact for ANY queries!!! They have no registered office no nor a national helpline number!!!
How legit is this company?? Why are we all falling for this??!
1.The company has no person to take the blame for fraudulent cases,
2.some company takes X amount of money from my account no one to refer for guidance!!!
3. Any update in interests rate and boom I loose they steal my money!!
4. A national company catering to millions of Indians with no actual human sitting behind the operations dealing with the CUSTOMER!!!

How?!!! And what happens (god forbid) credit card is hacked, dat leaked...etc and slice is literally telling us we are on our OWN.
