Capitec Bank refusing to release my hanging pre-authorised payment

Capitec Bank is just failing the online banking with Zara,on the 18 June 2020 I purchase online with Zara the amount was pre-authorized and deducted from my account.On the 27 June 2020 the same amount was deducted again meaning I was double charged for the same payment.I contacted on Twitter Capitec bank and Zara.Zara cited that Capitec bank is the one that is supposed to release the pre-authorized amount as it is still with them because Zara got the payment on the 27 June 2020.Capitec Bank is giving me a run around with a vague message with an “ I don’t care attitude “ and they ask me to call their call center.With what airtime?Because they are the ones who have my money and refuse to release it!
