Exceptionally Poor Customer Experience Investec Cash Investments

On the 15th Aug I accidentally deposited funds to my 45 day Money Optimiser account instead of my Money Tracker. I wrote to Investec Cash Investments straight away and asked them to correct the mistake. Snowy Mkhaliphi rep**** that my funds would be moved to your Money Fund Tracker account and value dated 15 August 2019. This never happened. I then wrote again to Investec and go no reply in 2 days. Its now month end and I don't have cash. When I called Investec they tell me it will take 24 to 48 hours to return my funds with interest to the Money Tracker account or I can pay extra to have it done immediately. This is shockingly poor service with no accountability or urgency to try and short out something that Investec committed to take care of.
