Refund of GST paid on Imports by foreign vendor

We had imported certain goods from Italy and while clearing the goods at Custom Station , its CHA paid the IGST on imports and mentioned our GSTIN on bill of entry. The vendor did not charge back the GST paid by him. Can we claim the Input Credit of such IGST paid by foreign vendor as the Bill of Entry mentions our GSTIN. All we have in documents is the Bill of Entry where under Importer details , our GSTIN and details are mentioned. And though the vendor has not directly charged back the amount but we have a whole project contracted with the them and we bear the cost of such project and definitely the vendor will consider this amount while charging the price.
