Thats very true Charan...as its clearly stated on their guidelines......
"In this case you should provide a Statutory Declaration claiming the reasons why you cannot provide a reference and explaining in complete detail what you did in this position.
This must be supported by HR Style references, recommendations from colleagues (with business cards attached), job contracts, pay slips and other relevant information that demonstrates employment.
Please note the assessor is under no obligation to accept this and you submit this at your own risk. Please note there are heavy consequences for those who submit a fraudulent statutory declaration."
However, you keep your fingers crossed and collect as much as details you can before filing the application. All the best for your battle......
Note: you can also get the reference letter from your manager on company letter head with contact information...this would also suffice the purpose.
