For Zolo IMPS transfers, would my unique virtual bank account(VBA) change in case I update the registered phone number with Zolo? What happens to the old account number

After updating the phone number, the user should only make payments against the new account (VBA). In case payment is done against the old account (VBA), the transferred amount would not be used for settling any Zolo charges. In such cases, the customer needs to reach out to the support team and request for refund
