Amount paid toPWRTrade without my authorisation

On 7 December 2015 I completed a Cheq / debit card dispute and e-mailed it to [Email Removed] about the amount of R3709.00 which was paid to PWRTrade on 3 December 2015. I received an automatic reply that they will sent me a sms notification. Nothing further happened. On 17 December 2015 I again inquire about the amount that was paid to PWRTrade (R3709) without my request or authorisation. Again received a sms stating that the client has 30 days to respond. It is now seven weeks since the first documents was send and still NO reply from FNB. Every time I sent an e-mail (and there were numerous) I received a automated reply that I must monitor my account after five days. Acc nr *** AJE Bosch. I've not only gain NO interest, two of my stop orders did not go through because of not enough funds. Therefore extra bank costs. Unnecessary!
