I want my Money Sanlam!

I opens a savings/investment at Sanlam last year and I have bees paying R500 a month since April 2019. I called them 2 weeks ago to find out how much I have saved so far, I spoke to one of their consultants named Palesa who than tell me that I only have R4800 saved!!!Which doesn’t make sense to me because I’ve been saving since last year and according to my calculations I should have R6000 saved up. I asked her how it’s possible and she said she’ll ask their finance department to sent me a detailed report of where the rest of my money went, well I’m still waiting!! It has bees two week, still nothing!! I am very disappointed in Sanlam, they are *****ing from people and I want all my money! Even their client service is disgusting!
