Unprofessional and rude behaviour

Nedbank Bedford Centre your staff are very unprofessional. I went to your branch yesterday and the lady (with the broken leg,) at the front firstly didn't have the decency to greet me. When I explained to her that the proof of account has the wrong account number, she says toe why do you select the wrong account number when I didn't print it one of your staff did it fore at the self help machine. I wasn't asked for which account in wanted it. She then says sit down I am still busy with some one else. I am a customer for many years and it's the first time I experience such horrible customer service. I also wanted to change my in contact number, I ended up just leaving because I didn't appreciate being treated like that. I am seriously thinking of closing my account and banking elsewhere.
