No response after 4 emails and 2 moths later

I sent the below email to information to *** on 16/05/24 and did not get a response. I sent a follow up email to the same email address on 27/05/24 and still no response. Another one on the 4th June '24. No response. I finally sent a follow up to *** on 15th June for an answer and still no response.

Why the lack of communication? Why is it so hard to get a response and why do I have to resort to HelloPeter to get a response from someone at Standard Bank insurance?

Here is my original email:

Good day, Please help me understand why my monthly installment went from R1600+- to R2000. I understand that an insurance premium was added due to the instalment agreement requiring me to have insurance, however I am being charged for 2 different additional products. One of which is added to my premium and one which is added to my remaining balance. R322.15 and R391.15. One of these charges is insurance, the other I did not agree to. I should have 1 more payment due of +-R1700 yet I have almost double this. Please advise.
