I'm so dissapointed with Nedbank

I am so dissapointed with nedbank I regret why did I stop using my fnb ..I have been calling for over a week now looking for sales person at home loan department because I want some help from them since I have home loan with nedbank, I've been told by 3 different people that they will send a request for someone to call me ,the 4th one gave me an email and I sent a request no response, I went as far going to Khayelitsha branch cape town,the guy who was assisting me I also know his name he said he will get an information and get back to me till today I have been waiting..I never felt so stupid about a decision of changing a bank by being convinced with empty promises....
