Standard Bank taking us for granted

I accidentally made a transfer of funds using Cellphone app and instead of putting in nine digit account number I put in eight but surprisingly the money left my account. I called and asked for the transfer to be recalled and I was asked to complete a form for that specific instruction. Firstly, the form I received for completion states that if the receiving acoung is held by Standard Bank the turnaround time for recall will be 72 hours (in digits) but in words it says 48 (forty-eight) hours. Nevertheless, I completed the form and sent it back, again when I called after the lapse of 48 hours I was told that the turnaround time is now 10 days. Despite having been assured that the amount could be recalled, on the 3rd working day I receive a message that the recall is unsuccessful because they cannot find the customer into whose account the money was paid and nothing is said as to the availability of the funds I transfered. This simply means I lost the amount of R1500.00 that I paid even if the money might be in the account held at standard bank. It is really shocking how a bank like standard bank would treat its clients like this. And what is worse is that I am a private banking client, charged so much monthly fees. And sadly, my account was charged R310.00 for the recall which means that I escalated my loss to R1810.00. This is bad banking practice I have ever seen.
