No Service

I called Nedbank call centre about 30 mins ago and was put through to one person after another. Eventually I spoke to Rubin, a supervisor, who said he would look into my dispute and refund and call back in 10 mins. Its now over 30 mins and I'm still waiting. Money was taken from my account *******ly and after 2 weeks I cannot get an answer as to when my dispute forms will be processed and refunded.
