Thanks for joining the Community and bringing up your concern, Muhammad. 

You can recover your Customer account by going the the Customers section under Sales.

Here’s how:

1. Go to Sales, select Customers from the left-hand menu.                                                    
2. Click the Gear Icon above the customer list.
3. Check the box for Include inactive to display all customers.      
4. Find the deleted customer.                                                                                                 
5. Click Make active to reactivate the account.
