Worst service from FNB!

I'm soo furious and feel abused by FNB!!!!I sent an ewallet on Saturday for R500 and I was double debited! On top of that the person I sent the money to could not withdraw the money because FNB has ewallet technical issues that they didn't even bother to communicate to clients!Now I've been on calls since Saturday with rude and sarcastic consultants who were not providing solutions.I have just been on a call now with another consultant who said the request that was sent on Saturday was only the R500 that was a duplicate..the other R500 that's in the ewallet account can be reversed but I will be charged R55!!How the hell am I being changed for a bank's incompetence???why wasn't there communication notifying clients that ewallet services are having an issue??I want my money back!!I'm now R1000 out plus the airtime I've been wasting on *********** and unprofessional consultants!FNB has been the worst bank to deal with this year!
