Can't get async and await working

Logic says: User 1 sends a message to User 2 via Server 1. Server 1 records it in DB (mysql) and sends the message to Server 2 to be sent to User 2. Server 1 responds to User 1 that message has been sent. While at the back-end (asynchonously) Server 1 keeps requesting Server 2 for the delivery of the message, when delivered, updates the database and set delivery status as delivered or failed (after few hours of re-trying).

But I don't think this code is working. Because database never gets updated.

SendMessage.aspx

protected void btnSend_Click(object sender, EventArgs e)
{
global g = new global();
g.CallUpdateSMSStatus(cmdSMS.LastInsertedId.ToString(), msgID);
}

global.cs

public async void CallUpdateSMSStatus(string strMsgID, string strMsgID)
{
await updateMessageStatus(strMsgID, strMsgIDServer);
}
public async Task updateMessageStatus(string strMsgID, string strMsgID)
{
global g = new global();
int timer = 10000;
int intStatus = 2;
// 2 - means Message Sent - Any other number finishes delivery request
while (intStatus == 2)
{
await Task.Run(() =>
{
intStatus = g.checkSMSStatus(strMsgIDServer);
//checkSMSStatus REQUEST SERVER 2 for status of message
if (intStatus != 2)
{
//Update Status in the Database
}
else
{
if (timer < 3600000)
{
timer *= 10;
}
Thread.Sleep(timer);
}
});
}
}

Yes, line 20 does its work as said in comment which is working. This code has been tested to work in synced mode, i.e. without async/await keywords.
Its in global because its common to more pages on application level.

But the code doesn't seem to work in async mode as in the code given.

Is there any code in your actual file, because line 20 has only one comment
//Update Status in the Database

Simple way is to place a debug break point at line 18 and check what's in intStatus.

One other suggestion, whay is this code in global? Why can't you create separate class and call it's method?

in global we only write application level events
