Outstanding payment

On the 9/07/15 I contacted Ms Palesa Mpeke regarding my investment policy as I needed money, Ms Mpeke asked me to forward her my ID number and initials. When I took the investment policy Ms Mpeke explained to me that i can access my money before its maturity when in need but there is a R400 fee I have to pay. The very same day Ms Mpeke responded to my request and told me that Mr Johan Plaatjies says i can withdraw up to R15000 from my investment and that Mr Plaatjie has forwarded me the necessary documents to complete. On the 10/07/15 I completed the forms and requested a withdrawal of R15000 and scanned back the documents to Mr Plaatjies. I didn't receive any acknowledgement from Mr Plaatjies whether he has received the documents or not. On the 15/07/15 i sent Mr Plaatjies an email asking if he has received my email with scanned documents as I have phoned Ms Mpeke the previous day. On the 16/0715 at 06:14am I received an sms from *** saying my Liberty Life payment of R10818.81 proceeds of Policy ***. I immediately sent Mr Plaatjies an email as i didnt request that amount and want to know where is the rest of my money. I have not received response or explanation.
