Bad service!!!!

I am so tired of waiting on a reply!!!! I app**** for a loan last week, and I haven't heard back, I have called everyday, more than once, every time they tell me the same thing. It's with Nomdisile, one smart one told me she is on leave, but they will reassign it. And everytime I call they tell me it's still with her, but a team leader will contact me before the end of the day. But NOTHING HAPPENS!!! Today I went to my branch and they called again to ask them to assist me and promised me it will be sorted out before the end of the day. Still nothing! I am getting sick of this. Don't advertise a service that you clearly can't deliver.
