poor service

On internet banking you have secure message where you request service from the bank and they state they will contact you within 24hours-My first message was sent and nothing happened in the 24Hours-I sent a 2nd and 3rd message whereafter they contacted me promising to increase my eap monthly limit for an important transaction-even received a message with ref,7067 on 02 April 2015 that it is done but nothing was increased when I log onto my internet banking-still the old limit nothing was done-I still log on more than a day later just to find everything is still undone-I did not expect such poor quality service from a bank-they handle our money that makes you worry if you think about it-maybe I must just close up the account and move to another bank!Time at the bottom is when I received message that increase was done
