Shocking client service

I receive a sms from you yesterday advising i could increase my credit limit. I went to the store today and provided 3 months pay slips. The employee said it was accepted but she would need to contact Head Office later (in a couple of hours). I then enquired what the process was and when would i know if i was successful. She said she needed to speak to her manager. I waited and waited and she came back and said her manager would be right out. I waited and waited. I then asked to change my email address. She contacted Head Office and we waited and waited. I was not informed of anything while I was waiting but the employee is on the phone and looking at herself through the glass divider. Why send me a sms if you don't want my business. Seriously shocking client service.
