If I could give them zero star I would do. They don't deserve any star because they are swindler. I promised them I will tell anybody about my experience. Worst presentation I've ever seen. I paid $ 480 for garbage. I rearranged the slides and rewrote the notes and no one gave me a fair solution. As a result, I couldn't view my presentation by the deadline and it cost me a lot of grades. I won't forget this for ever and when I meet anybody, I will tell him about this fraud.
