Statement request 2011

I requested for the statement from standard bank on the 24/03/2015 for 2*** account number:*** and I was promised that it will be sent to me within 5 days of which I did not receive by then, I complained everyday calling the call centre I even went to the branch itself and nothing was done. Then there was a lady by the name of Ellen Sebaea who sent wrong statement as she only sent me the statement for 2012 on the 20/04/2015 I rep**** that the statement is wrong as I requested the statement from 2011 since then I haven't heard anything from her she doesn't to respond to my email I called her she said she will get back to me which she hasn't and I logged a complaint with standard bank on the 09/04/2015 complaint number\:*** and I haven't heard anything from them as well
