Good day, Amit.
I'm hear what you're saying about your experience. As a new customer, it's important that you get the support you need. To ensure that your onboarding process is properly taken care of, I'm going to have to let you contact our QBO Support team again. This way, they can check the status of your callback requests, and to know if there we're callback attempts. They can also guide you a new schedule.
Let me know if you have other questions in mind. Take care and have a good one.
