Trying to get a settlement figure on my Nedbank account for the past 3 weeks.

Contacted Nedbank for a settlement figure on my Cheque account and have been told on several occasions that the letter will be mailed to me within 48 Hours at first. After contacting them back explaining that nothing had been received they then promised me it would be re sent within the next 15 min. I have still not received the statement promised to me. Apparently this is a common practice and several people i have spoken to also had similar experiences. you would think that they would really jump on this as full and final payment has been arranged.
