Bad customer service from rain

The customer care of rain is very poor, I made payment to wrong account which is also mine but don't have the router for it, so I have asked them to transfer the funds to the correct account so that I can be able to work since I need internet. There is no resolution or way forward just for that simple query instead what I get is their message that help is coming hang in there, even now. How must I hang in there when I need to work😡. Once you get signed with them they don't care about you!!!
