Not happy at all!!!

I have been trying to close my account with Absa now for 3 weeks. I went to the Edenvale Branch and was told I need to pay R 300-odd to have the account closed. I did not have the cash at the time so I went back today to close it and was told there is an amount of R 340 which they cannot pick what it is for that needs to clear. I was there for an hour trying to get this sorted. The closure amount now has gone up to R 740 - but the account cannot be closed because of this R 340. Also why must I pay so much to have my account closed. I have been with this bank for almost 10years - most of which I regret. Simphiwe ( consultant ) is really good with clients. If it wasn't for him trying to assist, this situation could've been worst.
