Bad Customer Service

My name is Zukiswa.My acvount number is ********** 688.I have a problem with Capitec Bank.They put my account on hold for the reason I don't know.They don't allow any transactions in my account when I did went to the bank they call the helpdesk almost an hour but no luck until I gave up and I was running out of time.How can they put my account onhold without contacting me because they should've contacted me first and ask what they don't understand.I really don't understand what Capitec is really doing to us.They are treating us like hell.Please feel free to contact me my number ********** 697.Zukiswa Ntezo.Your response will be highly appreciated.Thank you
