Please Verify My WhatsApp Account

My WhatsApp account linked to the number 03423077*** has been banned for about 5 weeks and I do not know the reason. When I try to open WhatsApp, I only see a screen saying that this account can’t use WhatsApp anymore, without any clear explanation. I have been using this number with WhatsApp for around 5 years and I was simply using my account in a normal way. I had two logins on my phone, one of them had some issues and when I logged in with the other WhatsApp, that account was also banned shortly afterwards. I have contacted WhatsApp support but I did not receive any helpful or clear response about why this ban was applied. I kindly request that my account be verified and reviewed again, and that the unjust ban be removed. If there is any specific problem, I also request a clear explanation so that I can avoid it in the future.
