Bhanzu — Not refunding the money

Hi I came to know this Bhanzu Math tution by Facebook. Then I approach customer agent, we spoke over the what up, paid full course fees with with the condition, if my child doesn't like in the future with in a month of time they would return me refund amount after prorated. But then when I approach the customer agent, she was not responsive, is giving me different excuses and divert me to another agent. The service is totally very very worst. I am worried so much whether will I get back my money. The owner is Mr Leelakantha Bhanu Prakash. Looks very cheating online platform.
