Absolutely NO Service from Standard Bank

We are a community group of residents who work hard to keep our suburbs safe - we use standard bank - however the service (or rather total lack of service) is just dreadful - It took us three months to get our debit order limit increased and we are STILL waiting to change some of our signatories (requested at the same time in November last year) - With over 2,100 homes to deal with - I think it is fair to say we have a fairly large amount of residents we can share our sad tale with - Just absolutely no reply to any of our requests?
