FNB Call center is useless

I tried to reverse a DO on their client service nr. Since Saturday I phoned them it cost me over R100 in airtime and still no service. Saturday Ive kept on the line for more than an hour , and when I got through the agent dropped the phone twice. Sonday I got through to an agent and she told me that they dont reverse on sondays. This morning I hold on for more than 20 min before the agent went through the process only to tell me that part of the system is down. so R135 in airtime done and yet no one helped me. the agent didnt even show a inch of remorse, only told me that I can keep talking to her and waste more of my airtime. Apparently they dont want to know HOW CAN WE HELP YOU, they need to change their slogan to HOW can we pee you off and annoy you more
