Standard Bank worst bank ever

Worst bank ever they blocked my account with over R17,000+ more than 30 days ago after I sent myself I small R1500 from my other bank into they bank they have been giving me long stories since the beginning of the month the other bank even closed the case 7 days ago because they saying that this case doesn’t make sense but Standard Bank continues to keep my account blocked and they have been telling me for 15 days that a investigator is going to call me I’ve been waiting 15 days for a investigator to call me to open my account I’m sick and tired of this bank who treats people like they are nonsense whereas even when the investigator does call he says hello am I speaking to Mduduzi then he turns off the call
