Customer Service Team Wrong Information and unhelpful serice.

​"When the My BillBook team member couldn't satisfy me, I requested him to have me talk to his senior. He got his senior on the line, and after two minutes the senior attended the call. But I kept saying 'Hello, hello, hello, hello' from here, and there was no answer from the senior's side, even though I could hear their entire team's voices on the phone, and then he disconnected the call. I have been using their software for 4 years and have already paid in advance for the next 5 years."
