DOUBLE DEDUCTION FROM FNB waiting a week for a response!!!!

I am so sick of trying to contact FNB. To put things into perspective, I have a little personal loan with FNB. On the 22nd Aug i got deducted R1597,41 and again on the 24th. Both deducted from my account but only one of the amounts reflects on the personal loan. I havent authorized two deductions to take place in Aug and all i want is my money back!! I used the FNB secure chat on the a week ago and they advised due to me having a new phone, my device isnt authorized yet and they suggest i go into a bank... Fair enough last week Monday i informed my manager i will be a bit late and went to Canal Walk's branch just to be put on a phone to a number (not sure why the agent in the secure chat couldnt just tell me to call) anyway........ waited so long eventually picked up, i chatted to a lady Bronwin Khano and she told me she logged a ticket and i should call back next Thursday (today) to follow up. Since 9am this morning i have been calling and all departments keep transferring me because they cant seem to find a Bronwin and there's no update on my double deduction!!!! Eventually find Bronwin and i get transferred to her a couple of times just for these people to drop the call on me about 5 times. I dont understand why i have to wait 7 to 14 days for an update, mission myself and call a million times to get feedback back on money FNB decuted!!! which isn't my fault... all i want is my R1597.41 back into my account and get feedback instead of me running around for feedback as to why FNB deducted twice!!! I am fuming.. Why do i have to fight and mission for my own money? we had an agreement FNB!! a signed agreement stating our debit orders which is ONCE a month!!!!!!!

Please get back to me asap. I cannot phone the entire day as my job requires me to attend loads of meetings!! please email me on *** with feedback and a plan to get my money back ASAP!!!!!!!!!!!!!!!!!!!!!!!!!! thanks!!
