Frankinn air hostess training institute - Request for cancellation of admission and refund fee

Sir/madam,
I got a call from frankfinn airhostess training institute and they told to attend a free seminar program.Then after seminar they told me that you are selected for the course.After that they told me about the admission fee and told me to pay at once otherwise I will miss the admission.They brainwashed me by showing big dreams and forced me again and again to pay the admission fee i.e.***** rupees.I told them that I will come with my parents tomorrow and i will take the admission but they denied they don't allow me to take time and talk to parents.Somehow I managed the fee and I paid to frankfinn airhostess training institute.Now due to financial crisis in my family I cannot afford such a huge amount so I want to cancel my admission and want refund of my admission fee.I lost my father and now I have to take the responsibility of my family.so please sir help me with solving my problem and I hope you will look into the matter
