Poor correspondence by Standard Bank

Loyal customer of Standard Bank. Recently thought of applying to increase my Revolving Credit facility. There is no real channels to apply or contact online as with other banks. Decided to email them with replies and promises that someone will contact me. Fortunately have all those emails, if they decide to sugar coat it. Sadly....it has been almost a month now.....guess what....still no call or attempt by anyone to contact me. Disgusted.
