Standard bank

On the 9th of June I got a phone call from standard bank they claiming there's ***** on my account I need to come in renew my cards . I went in to renew my cards and open the ***** case case and I got refunded R900 then on the 13th of June standard bank phones me to tell me my credit card is ready for activation send me a link to verify that it's me and the amount of R7000 went out of my bank account I immediately phoned standard bank and gave them all the details of what happened and they opened another ***** case close my check account and my credit card and blocked my app for the rest of the month resulting in not paying my rent not having food as I'm unemployed. as that R7,000 was my startup for my small business!! Only on the 30th standard bank says to me they cannot reimburse me and the ***** case is resolved
