Pathetic service from Nedbank Fourways Mall

I have been experiencing problems with my cellphone and internet banking , I was told to reset the password but it kept giving me the same problem and ended up blocked. I then went to Nedbank Fourways mall this morning and was assisted by Sindi who gave me the opposite of what customer service is. I spent more than an hour waiting for my query to be resolved and in that time she never bothered to update me ,I kept asking her on the progress and she said that she sent an email and awaiting respond,I then asked her to please do a follow up call to the department that she sent the email to and she said that they only communicate through emails which I found very weird. Sindi then advised me that the system was down and didn't know when it would be sorted out and told me that I can go home and she would call me with feedback. After awaiting for the call for more than 3 hours I then took the initiative to call the bank and asked to speak to Sindi and I was put on hold and the call would end up cut several times. She then called me after I have attempted calling her and told me that that system was still down. I am beyond gutted by the pathetic service that I got from Fourways mall and Sindi and would like my query to be sorted out causing calling them is just a waste of time.
