Bad attitude from the Home Loan call centre

I have been struggling to get a further loan on my home loan, and many times I have called the call centre and I am greeted with a stinky attitude from the other side. At first I thought I got a rotten apple, but when I called a couple of times more and spoke to different ladies, they all had terrible stinky attitudes!! what has happened to Standard Bank's brilliant customer service? has it gone bad an rot? why are they employing these horrible people? is it cheap labour? they seem to come from a very uneducated background, none of these ladies treated me as a respectable bank customer!! in fact they way they talked to me made me feel like a ********! the one lady yesterday, for example, carried on talking and wouldn't give me a chance to talk, eventually she just told me to go to my nearest branch with my paperwork and talk to someone, that was her advise/solution to me!!! I sarcastically just said out loud (maybe she was deaf?) "YOU HAVE BEEN SOOOO HELPFUL!!!" what has happened to Standard Bank? I am going to switch my bank accounts and my home loan account to Capital Bank, I hear they are fantastic!!!
