Non existant customer service

I have recently been persuaded to change bank (from Bank Windhoek to Standard Bank), with a truck load of promises on how their service will be so much better. Not only has none of these promises materialized BUT I can get no feedback whatsoever on services, documents, changes requested. Every time I call the bank I am told 'I will get back to you', only to call again the next day because no one thought to provide me with feedback. SO gatvol for Standard Bank....wish I could change back!
