Terrible service yet again

Went to close my account on the 14h of December 2015. An account that I paid and settled the 12th of may 2015 already. I only just found out that the account is still open and now reflects badly on my ITC because it is apparently on arrears. This is unacceptable and because of the bad service and standard bank not doing their work I was rejected for a homeloan and lost out on buying property all because they can't do their work. I want my accounts closed and my name cleared on ITC immediately that was supposed to be done in May already!
