Waste of time!

I was called by a lay from fnb a couple weeks ago who was offerring me a credit card, I told her that someone else already did a check and the interest rate was too high and I declined the offer. She then told me that she cannot pick it up on the system but if I could give her a chance to do a check and she will see what she can do on the interest rate for me, up until now I did not get a call or email from her and I told her to email me feedback. I want to speak to a manager in this department and I will like to voice my concerns with him. If he/she cannot get ahold of me telephonically leave a voicemail or drop me an email please. I await for a response and should I not get feedback I will do a switch over to another bank that can offer me better service!
