money market call account

I have recently opened a money market call account with Standard bank, why does it take over 5 days for for an internal transfer from my savings account to my cheque account to be available? I'm still waiting for the amount to be available in my cheque account but nothing yet, I was told upon opening the account that I would have instant access to my money from the money market call account. Really starting to feel like a steve from standard bank, this is just 1 example among many in the past couple weeks that has made me think about moving over to FNB. Such a hassle to switch banks though, thinking it may just be worth the hassle though.
