Bank is Asking for INC20A eForm or Certificate but I only have INC20A Challan

As I said, my bank is not accepting only MCA receipt for INC20A filing. They are also asking for eForm or Certificate of Commencement of Business. I downloaded eForm from MCA website multiple times and it is corrupted everytime. There is no problem with other documents but my INC20A eForm is corrupted. What can I do? Please help
