Laravel Controller

I have a TbookingController in User folder and another TbookingController in Admin folder but when I want to insert data into database using TbookingController in User folder, it does not work because it is only using the TbookingController in Admin folder. Please any help?

--------------------------------The Error------------------------------

Method 
App\Http\Controllers\Admin\TbookingController::store does not exist.

-------------------------------Tbooking Route---------------------------

Route::group(['namespace' => 'User'],function(){
  Route::get('trip','TripController@show')->name('trip');
  Route::get('tbooking','TbookingController@create')->name('tbooking');
  Route::post('tbooking','TbookingController@store')->name('tbooking.store');
});

----------------------------TbookingController in User Folder------------

<?php

namespace App\Http\Controllers\User;

use Illuminate\Http\Request;
use App\Model\user\Trip;
use App\Model\user\Tbooking;
use App\Http\Controllers\Controller;
use App\Http\Controllers\User\TbookingController as UserTbookingController;

class TbookingController extends Controller
{
    public function create()
    {
        $trips = Trip::all();
        return view('tbooking',compact('trips'));
    }

    public function store(Request $request)
    {
        $this->validate($request,[
          'name' => 'required',
          'email' => 'required',
          'gender' => 'required',
          'mobile_one' => 'required',
          'mobile_two' => '',
          'activity' => 'required',
          'date' => 'required',
        ]);
        $tbooking = new Tbooking;
        $tbooking->name = $request->name;
        $tbooking->email = $request->email;
        $tbooking->gender = $request->gender;
        $tbooking->mobile_one = $request->mobile_one;
        $tbooking->mobile_two = $request->mobile_two;
        $tbooking->status = $request->status;
        $tbooking->save();
        $tbooking->trips()->sync($request->trips);

        return redirect(route('tbooking'));
    }
}
