Bad Staff Attitude

We are customers of Standard Bank for 26 years, and never received such bad service twice from the same consultant, first was at enquiries were we left the bank after 95 minutes with only 6 customers before us in the queue the consultant told us that every person is entitled to his own opinion after we raised the issue of the waiting time in the queue while he was playing around at the tellers with only 1 consultants to assist, the second time we were waiting upstairs and enquire about the air conditioning which was off and the same consultant was laughing and joke about our request to his colleague to put on the air conditioning, the air conditioning is not use because the staff is getting cold, we have informed the staff member that we will report him and he said that we should feel free to do so.
