FNB UNAUTHORIZED deduction!!!

Extremely annoyed right now. I have spoken to 5 different consultants or more, put on hold so often, told I am being transferred (either they drop the call or send me to different departments), I explained my query literally 5 times.. ran out of airtime because of this!!!!!!!!!!!!!!!!! To start this all off, FNB deducted an unauthorized amount in the middle of the month for a personal loan I have, this was not agreed upon!! It has been agreed that it will be deducted at the end of the month. How does one deduct money in the middle of the month. I chatted to a consultant last week Wednesday regarding this and she put in an escalation that the money gets reimbursed latest today which is the 7th business day. I have still not received anything, all I want to know is if this amount will be reimbursed today and if all is in order!!!! I have been unemployed for 3 months and deducting cash without authorization in the middle of the month is unacceptable!!!!!!!!!!!!!!!!!!! Thanks freaken FNB for wasting my airtime, transferring me to a million people (none that can help) and for having your secure chat so useless that these people on the secure chat cant even check this for me!!!!!!!!!!
