tense - Present perfect or present simple

I want to order something on the internet. I realise that I have lost my password, I have asked for it but it has not reach me yet.

Please let me know if "ask" should be present perfect as it relates to the loss of my password or present simple. I think present perfect is better. Maybe "realise" should be present perfect too?

Now the same scenario in the past:

I wanted to order something on the internet. I realised that I had lost my password, I asked for it but it had not reached me yet. I wanted to order something on the internet. I realised that I had lost my password, I had asked for it but it had not reached me yet.

Same question for "ask" past simple or past perfect. I think past simple is better.
