BharatPe — Change Bank Account details

I have my own savings account link in Bharat Pay but since all this work is done by our company I want to register the company's account instead of my savings account so either reset my PAN card or enter the bank details of the company. Also, when I install the Bharat Pay application on a new mobile and register our company's bank details, I get the message that your account is already linked. Let me know what to do in the above case
