Investment

I am very unhappy with how old mutual do things, I opened an investment with them, saving every month R1000, then June this year they increased my money to 1049.99 without letting me know. I have now canceled it due to work changes and they will not give me the full amount that they have been deducting, I mean like this is my money not a policy how can they charge me so much,,, I will never recommend it to anyone as this is day *******..
