 I am from Nepal, who contact online astrology last year. I have shared my problem then asked if he can solve it. He told me he will fix it by worship method but it will charge. I had paid Indian Currency 31600 via bank transfer but after receiving cash he started to cut off call, massage. It's clear that I have been cheated.
