Nedbank Homeloans - NO SERVICE!

Tried to call Nedbank Homeloans and after calling the number on my latest statement and being 'verified' I was told to phone a different number. After getting through, the next all-centre agent had to verify me again and placed me on hold - where she left me for more than 20 minutes! All I need is information on where to send a specific request and Nedbank has to turn it into the most frustrating and time consuming exercise, with NO result at the end of a very long call! Nedbank's typical 'service' levels at work, once again!
