Satrix 40 delaying

I have an account and I normally deposit every month to it. This month I made a deposit as usual but unfortunately at Satrix they haven't updated my fund records it has been 7 full days now. I reported and I was requested to provide proof of payment of which I did, they then asked if I can resend the proof from the online app and I did so. the agent that was helping Cornelia then said the address I resent the proof to isn't theirs, now I am confused because that was from one of their communication from the general inbox email address. The only thing I need is for the money to reflect on my account and I am running out of time to invest.

please
