Transferred funds to incorrect account

I transferred money mistakenly from my discovery card to what i thought was my standard bank account only to later realise i transferred it to standard bank card. Discovery can not do a reversal and ive spoken to so many people at Standard bank already its too the point of ridiculous and no one can assist me. I need someone who can just allocate where the money is and transfer it to the correct account or just do a reversal back to my Discovery account. How difficult can this be when ive provided all the relevant information. I keep receiving case numbers with it being resolved when nothing has been resolved. Can somebody from standard bank just go the extra mile.
