  1. Hello, my name is Aisha Nayla, prey to fraud at the hands of fake lenders. I lost around Rp300,000,000 because I needed a large capital of Rp300,000,000,000. I almost died, I had no place to go. my trade was destroyed, and in the process I lost my child and mother. I can't stand this incident anymore. Last week I met an old friend who introduced me to a good mother, Mrs Christabel Missan Loan Investment Company, which finally helped me get loan of  Rp500,000,000,000 loan

     Good mother, I want to take this opportunity to express my gratitude, and may God continue to bless the good mother Christabel Missan and my friend. I also want to use this opportunity to give advice to fellow Indonesians, that there are a lot of fraudsters there, so if you need a peace and security loan and anyone who needs an urgent loan should be quick, contact Christabel Missan via email christabelloancompany@gmail.com
