Are you trying with PC or phone?
If its not possible from both then please go to your bank branch and ask them to send you the pdf file. Most banks give it the same day.
Since I am unable to download bank statement of 9 months, what do you suggest me?
I had statment of three months from date of deposit, I have sent it them already
But I don't know if they are going to resolve the issue
Their support team is full of idiots, they didn't clearly that situation when I was asking they everyday
I got all this clarification after this complaint
The issue is - it’s left your account you can see that, but maybe they haven’t received it and your bank failed to credit it back to your balance. This is why they need to see the transaction so they can investigate whether or not the money did land their side.
