unsuccessful withdrawal

Good day, I hope this e-mail finds you well. I need help regarding an unsuccessful withdrawal in Capitec account number: ***. Mr S Badule at Ref: Spark ATM Chillers Khayelitsha WCZA. I tried to withdraw an amount of R2000 but the transaction was unsuccessful, but still went through from my account. I reported this at the branch and was told to wait for 7 days. normally when such error occurs it reverses immediately. Unfortunately I find it unfair for my brother's money to take so long to be reversed especially at this time of the year. please assist. Thank you Sithini Badule
