FNB as helpful as loadshedding

I logged a dispute against a online purchase i made on the 22/11/19 via the FNB app, the order was immediately cancelled and i have sent all relevant documentation to the *** as per one of several useless phone calls made to the relevant department, we are now at 9/12/19 and again today i was given the run around by the useless *********** staff that are supposed to deal with my account issues, i am out of pocket of R1643.28 and no one seems to give a hoot about following through on their jobs because no one was able to give me any info regarding this dispute, i then tried unsuccessfully to speak with a manager or team leader as per usual they dont speak to customers.
