Please Unban My WhatsApp Account

My WhatsApp account with the number 9437457*** was suddenly banned. I first saw that my account was banned on 16 July, without any clear explanation given to me. I contacted WhatsApp support by email about this issue, but I did not receive any clear answer or explanation about why my account was banned or how it can be restored. I kindly request that my WhatsApp account be re-activated as soon as possible, or that I am at least given a clear explanation of the reason for this ban and what I can do to recover my account.
