DISSAPOINTING SERVICE

Im so dissapointed about African bank branch service. I received a call from the call centre on the 03rd of June from sales dept and the lady I spoke to did a credit card application online and got approved & she aske me to go to the branch to submit documents and I was told that on Saturdays they close at 1pm. I was at the branch at 12:40 and had to wait for a consultant because there were 3 or 4 people waiting and by the time I got to the consultant it was already 1pm and the first thing the lady said to me was \ If it an application I wont be able to help you because we close at 1pm? Then I told her that the application was already done I just need to finalise and she told me they still have to re-check and it will take 45min and it already 1pm told her that I dont have a problem with that because I dont get time during the week because i finish at 5 and 12 on saturdays so I have to do it coz im already there. She then told me again that it already 1pm she wanna help me but she cant because she will be holding up other staff who wanna leave?? How can a client who is bringing in business who was there before closing time be "technically told that he is holding everyone up? """
