cheque account quiry

I opened a cheque account with the bank last year and went back to close it again in 2 months, apparently they say I didn't close the account and what's worse is that no one bothered to call me that my account is in areas they just decided to let the bill pile up to R2800 then they hand it over without calling me. They have my cell number, work number, postal address, physical address and I still bank with them but no one bothered to call me early. Now I'm still waiting for the branch manager to call me, tired of this bank now no one is willing to withdraw the statement even head office apparently it is said that they can't but they put me under administration soooo ****ed off with this bank
