Pls house, I need your advice!!

My elder sister went to deposit the sum of 100k in her bank account, since December she didn't receive the alert up to today. It's was UBA, Redemption Camp. She has been going to the bank since December, they kept telling her to come back. She went to their Corporate head office in Marina, she was told it's will be resolved. The annoying part was she was told the teller number was invalid. Something she picked at the bank. Pls help, we need justice. Its her hard earned money. Pls help repost!!
