woocommerce offtopic - Programatically Remove Item from Cart Not Working - Needs Page Refresh

I am trying to add a free product to the cart if the order total is above $199.99

I have achieved this and it is working. The issue is that I need to remove the product if the user then deletes an item from the cart and goes below $199.99 again (to prevent gaming the system).

What I have seems to be working. The problem is that it seems I need to click 2 links before the REMOVE FROM CART action seems to be working (or refresh the page).

What is causing this? Can the remove action be accomplished with AJAX by any chance?

// -------------------------------------------

    $cart_total = 199.99;   

    if ( $woocommerce->cart->total >= $cart_total ) {
        if ( is_user_logged_in() ) {
            $free_product_id = 339;  // Product Id of the free product which will get added to cart
            $found      = false;

            //check if product already in cart
            if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
                foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
                    $_product = $values['data'];
                    if ( $_product->get_id() == $free_product_id )
                        $found = true;
