Standard Bank just don't care about clients anymore - they don't need our service anymore

Being a client for over 20 years and this is the service you get! No wonder more people is moving their accounts to other banks, and if I keep getting this service I am also going to move my business account to a more reliable bank. Every month now I must post a complaint, because you did not release payments into my account after my client swiped his card using your card machine "suppose to be stress free and save BUT NOW is actually frustrating". The machine was used on Saturday 8 June for payments it is already the 11th June and still no payments released into my account. I have phoned Standard bank yesterday and you promised it will be in my account today 11 June - STILL NOTHING and if I try to phone you again there is NO ANSWER AFTER HOLDING THE LINE FOR 10 MINUTES AND TRIED TWICE. Now my question is, should I now start taking legal steps against you? If these payments is not released into my account today, I will take steps against you!
