Definitely closing my account after this fiasco!!!

Today an attorney paid funds into my account from her standard bank account to my standard bank account and even though i can see the funds in my account, its not available because standard bank has a ridiculous rule that the funds will take 24hrs to clear......standard bank has basically *****ing my money and earning interest on funds which does not belong to them. Is your IT systems so outdated that it cannot even recognise a transfer from another standard bank account??? How are u keeping uo with technology, i also understand risk involved when dealing wjth new accounts, but my account is not new to u and even my salary gets deposited into this account.....i will definitely be moving banks after this fiasco, i now need to pay a hospital bill today which i cannot do in order for my dad to have surgery because of ur old systems!!!! Keep up with technology....standard bank is reminding me of the times my dad still banked with them and had a bank book and not a card.....i even called ur call center and after bekng out on hold for 30 mins i got cut off
