Waiting for business banker to call me since 29th of April

I don't know why, but apparently I must wait for Julius Khoza to assist me on business banking app. I just wanted to just add a 2nd account to my savings account. I went to the branch at festival mall on the 29th of April, they said they left a note to my banker to call me, they cannot assist. I waited until the 2nd of May, and called the business banking for help, they also told me that Julius is my banker, and he will call me as soon as he can, and refused to give me his office number, but copied me on the email they sent to him to call me. On the 7th, I responded on that email that I'm still waiting for him to call me, and he responded to ask what time, I confirmed that anytime. He didn't call. The 9th of May, he sent another email to ask how much I want to invest, I explained that I'm not investing, I just want to open an account, and that was the last time I talked to him. So I don't know if that means when I'm not investing, I'm not important or what, and why should I wait for one person for a very small thing, if the person goes on vacation, everything will stop. No one will assist. I'm still waiting till today. Very 👎
