First of all you should always check if your horoscope and do these things. As per your horoscope your chart is very weak on Investment front and also any kind of partnership. The period you are running of Rahu Mahadasha and Saturn antardasha is not since May 2014.
I feel you will get your money back in instalments. You need to pursue her and only then you can expect something.
