Poor service greenback rewards

I am utterly disgusted with the service i have recieved from nedbank lately. Firstly my cards expired and i recieved and sms to collect my new cards at randburg branch only to find my greenbacks rewards card there and my other 2 cards were at northgate branch which i had to drive there to collect. The staff at randburg couldnt even call ahead explain the situation so i wouldnt have to wait in yet another queue. I have been doing some huge transactions using my platinum amex card to collect greenbacks i called in to enquire why i have not recieved my greenbacks for my card purchases at the casino they say because they dont give rewards for casino chips yet when i deposit the caah into my account from the casino they happy to take exorbitant cash deposit fees i have paid over 10k in fees in the last 6 months then they say the previous rewards that they assigned to me were in error and they will be reversing them. They couldnt even get the manager to call me they asked the call center person to call me. I have been a platinum acvount holder with Nedbank for over 5 years and have not once got a call from any banker at all. This service is disgusting. If i dont get a sincere call from a manager at nedbank i will be closing my account and moving back to FNB.
