Dis-investment

I made a dis-investment in March this year on my savings. It was discovered that I had some cash to withdraw. Well I took it, submitted my bank statement. Everything seemed OK. 7-14 days passed with no money in my account. I made an enquiry. They said there was a fault in my account. Fast forward I forwarded my new banking details last month (October). They said they will process my payment. Till to date I have not received any amount.
