Laravel how to remove purchase limit?

Question

Laravel

Good day, I have such a problem. There are 4 packages. by levels. and it is arranged so that having bought the 4th level at once, you will not be able to buy the 1-2-3 level. Here is the code, how to remove this restriction?

public $sentMoney = 0;
    public function createOrder(Request $request) {
        $result['message'] = 'Временно недоступно';
        $result['status'] = false;
        if (!$request->packet_id) {                        
            return response()->json($result);
        }
        if (!Auth::check()) {                
            return response()->json($result);
        }
        $price = 0;
        $order_code = time();        
        $packet_old_price = 0; 
        $packet = Packet::where('packet_id', $request->packet_id)->first();       
        if (!$packet) {
            return response()->json($result);
        }
        if ($packet->is_upgrade_packet) {
            $is_check = UserPacket::leftJoin('packet', 'packet.packet_id', '=', 'user_packet.packet_id')
                ->where('user_id', Auth::user()->user_id)
                ->where('user_packet.is_active', '=', '0')
                ->count();

            if ($is_check > 0) {
                $result['message'] = 'Вы уже отправили запрос на другой пакет, сначала отмените тот запрос';
                $result['status'] = false;
                return response()->json($result);
            }

            $is_check = UserPacket::leftJoin('packet', 'packet.packet_id', '=', 'user_packet.packet_id')
                ->where('user_packet.user_id', Auth::user()->user_id)
                ->where('user_packet.packet_id', '>=', $request->packet_id)
                ->where('user_packet.is_active', 1)
                ->count();

            if ($is_check > 0) {
                $result['message'] = 'Вы не можете купить этот пакет, так как вы уже приобрели другой пакет';
                $result['status'] = false;
                return response()->json($result);
            }

        }
