fnb connect debiting funds into my account on a date i didnt argree on

one of the call agent called me introducing data package to me I was keen on their data package I told the consultant when to dedicate the total amount, they need to activate. fnb went ahead dedicating the money from my account after me telling them when to dedicate it. the funds that were in my account was going to be used for my electricity and now my electricity is going to be cut because the consultant did not pay attention to my instructions. I have a 3 year old who's going to be stuck in the dark for 21 days because we have to wait for them to figure out what is the matter. I have called several times regarding this matter, non of the team leaders or managers have given any feed back with regard to this matter. at this point I feel like fnb was after a sell but nothing else. call centre number 147
