Needed feedback regarding advance account balance

I had a query that I logged dated 05/11/2015 regarding the balance due on my account, wh is the balance still the same as the year before and why I haven't receive any statements from they offices. Anna from Customer assist came back with half the feedback that I requested on my query and when I sent a follow up e-mail I still didn't get a response from the Department. I copied they escalations Department as well and today sent another follow up mail but still no response, its ridiculous how they have been treating me, I feel like closing my cheque account and open another account with another bank institution. I have been banking with Standard bank for almost 13 years now and have had this account since I joined the bank. I'm really very unhappy about the type of service I've been getting ever since I'm no longer and employee of the company!!!
