Please, read my comment to the question. You can not read (load) multiline header through the OleDb provider.
If you would like to read data from sheet starting from second row, you have to define it in
SELECT
statement, for example:
SELECT * FROM [Sheet1$a2:d]
For further details, please see:

Alternatively, you can read Excel data using:
-
OpenXml sdk[

-
EPPlus library[
