Help I keep getting error I am new to Arduino =( expected '}' at end of input)

#include<SoftwareSerial.h>
SoftwareSerial mySerial (5, 7);
int sensor_Pin[] = {8, 9, 10};
int led_Pin[] = {11, 12, 13};
int level = 0;
const byte sensors = 3;

void setup()
{
pinMode(sensor_Pin, INPUT);
pinMode(led_Pin, OUTPUT);
mySerial.begin(9600);
Serial.begin(9600);
Serial.println("Critical Level");
}
void loop()
{
int val;
val = digitalRead(sensor_Pin);
if (val == LOW)
{
digitalWrite(led_Pin, HIGH);
level = sensors;

}

else

{

digitalWrite(led_Pin, LOW);

}

Serial.println("Water level");

switch (level)

{

case 1:

Serial.println("HIGH");

break;

case 2:

Serial.println("AVERAGE");

break;

case 3:

Serial.println("LOW");

break;

default:

Serial.println("NO WATER");

break;

}

delay(50);

{

}
void SendMessage();
{
mySerial.println("AT+CMGF=1"); //Sets the GSM Module in Text Mode
delay(1000); // Delay of 1000 milli seconds or 1 second

mySerial.println("AT+CMGS="+639975474330"\r"); // Replace x with mobile number
delay(1000);

mySerial.println("Water At Critical Level.");// The SMS text you want to send
delay(100);
mySerial.println((char)26);// ASCII code of CTRL+Z
delay(1000);
}

  void SendMessage();
  {

Oops

     break;

  }

  delay(50);

  {



  }

And again.
