No one is responding to my query, whenever I have doubt my mentors start ignoring me don&#039;t try to focus and clear my doubts - they just tell me things like beating around the Bush. I feel stucked after purchasing  the investment banking nano degree program as no one is there to clear my doubts , how will i get the job if I will not become well versed in this, I want the solution to this or give me the refund.
