WP WooCommerce Smart Coupons Customisation

My website is creating coupons using the plugin Woocommerce Smart Coupons. I also use the plugin WooCommerce Price Based on Country Pro to change the currency depending on where someone is in the world. When a customer makes a purchase, they are emailed a Booking Voucher automatically which they use later. I have attempted to use hooks in [login to view URL] to create a new type of discount code – ‘Booking Voucher’. Unfortunately, it didn’t work correctly: in My Account it showed the wrong ‘discount type’; the autogenerated emails didn’t show the currency symbol and the subject and content of the email needs to be edited. Also I need to be able to be able to hide ‘Coupon Receiver Details’ box in the checkout. Please message me for a more detailed description.
