Sa100 self assessment form

I live outside the UK. For many years I have received the paper SA100 form by post. This year it didn't arrive. I called the helpline twice to have it delivered and it still hasn't arrived. This has gone on for 2 months. Why has it not been sent?

Hi,
I am sorry you are having issues in receiving your paper tax return.
If still not received then you will need to contact HMRC to issue Self Assessment: forms ordering
Thank you.
