Form does not send input to MySQL in VB

Question

So I wanted a user to input data into the form, after clicking "Create", it shows that it successfully added the data. However, it doesn't appear in my MySQL Database, it only triggers the auto-increment of ID, other columns have no data.

Here's the code for the button CREATE:

Imports MySql.Data.MySqlClient

Module DBConnection Public Function strconnection() As MySqlConnection Return New MySqlConnection("server=localhost;user id=root;password=;database=bankmanagement") End Function Public strcon As MySqlConnection = strconnection()

Public result As String
Public cmd As New MySqlCommand
Public da As New MySqlDataAdapter
Public dt As New DataTable
'for create or add function
Public Sub Create(ByVal sql As String)
    Try
        strcon.Open()
        With cmd
            .Connection = strcon
            .CommandText = sql
            result = cmd.ExecuteNonQuery
            If result = 0 Then
                MessageBox.Show("Failed to save data!", "ERROR", MessageBoxButtons.OK, MessageBoxIcon.Information)
            Else
                MessageBox.Show("Data has been saved in the database (Please click the Refresh button)", "SUCCESS", MessageBoxButtons.OK, MessageBoxIcon.Information)
            End If

        End With
    Catch ex As Exception
        MessageBox.Show(ex.Message)
    Finally
        strcon.Close()
    End Try

End Sub

This is my SQL Query for adding something on the form:

Private Sub SButton1_Click(sender As Object, e As EventArgs) Handles btnCreate.Click
    Try
        Create("INSERT INTO customer (cust_name,cust_add,phoneNo) VALUES('" & cust_name.Text & "', '" & cust_add.Text & "', '" & phoneNo.Text & "')")
    Catch ex As Exception
        MessageBox.Show(ex.Message)

    End Try
End Sub

What is the possible error here? Although the program runs in succession?
