Laravel Pagination returns wrong order!

Hi everyone.

I'm working on this new project, and I'm so confused with this problem. So, I want to get data using paginate() and before that I want to order data by created_at > ASC.

I see, it returns data with opposite order! No matter if I use DESC or ASC, in both case, result is opposite. No matter if I order data by created_at or by ID. It always returns from down to top!

I attached the codes I wrote to get and order data and Eloquent relationship I used.

If anyone has any idea why this happens, please help me. Thank you.

Relationship in USER model

public function customers () {
    return $this->hasMany(Customer::class, 'id');
}

Get & order data customers data

public function listCustomers () {        
        $customers = User::with('customers')
        ->select(
            'id',
            'fname',
            'sname',
            'email',
        )->orderBy('created_at', 'DESC')->paginate(10);

        return response()->json(['customers' => $customers]);
}

And in VUEX Store, inside an action, I fetch ordered data

state: {
        customers: [],
        loadingCustomers: false
},
    getters: {
        customers: state => {
            return state.customers
        },
        loadingCustomers: state => {
            return state.loadingCustomers
        }
}
mutations: {
        getCustomers (state, customers) {
            return state.customers.unshift(customers)
        },
        toggleLoadingCustomers (state, status) {
            return state.loadingCustomers = status
        }
}
actions: {
        getCustomers({commit}) {
            commit('toggleLoadingCustomers', true)
            axios.get('/admin/customers/list').then(response => {
                    response.data.data.forEach(function (customer, index) {
                        commit('getCustomers', customer)
                    });
                })
                .catch(err => {
                    console.log(err)
                })
                .finally(() => {
                    commit('toggleLoadingCustomers', false)
                })
        }
}
