Restore My WhatsApp Account

I have been using a WhatsApp Business account on my Android phone with the number +91 93602 87*** mainly for customer support and digital marketing. Through this number, customers contact us with queries about our services and we respond to them regularly. Until around 12 a.m. last night my WhatsApp Business account was working normally. This morning I discovered that the account is in “restricted” status and I can no longer use it. I have not received any email, notification, or clear explanation from WhatsApp about why my account has been restricted. Because of this sudden restriction, I have lost access to a large number of important customer contacts stored in WhatsApp Business, and I am unable to respond to ongoing customer queries. This situation is causing serious disruption to my work and is very frustrating for me. I request that my WhatsApp Business account be urgently reviewed and restored. If full restoration is not possible, at least I ask for help to recover and export all my contacts and chat data from this account, and for a clear explanation of the reason for this restriction.
