FNB *****ing My money

At FNB Maponya Mall A reversal of $10.00 was made and transacted successfully as R140 00 from Hotforex. And there are few pending withdrawals which are still being held. Another reversal was made of $40. 00 this morning FNB Maponya Mall converted the $40.00to R40. 00 in my account... In what universe is ZAR and USD the same rate.. I want my money and tired of complaining.. This is the third time this month. Your service sucks it's unprofessional
