I have an account in your bank.

[tufguy]

To the bank manager.

I have an account in your bank.

I am a customer in your bank.

I am at your bank.

I am in the bank.

Please check.

 

[emsr2d2]

I have an account with you.
I have an account at your bank.
I have an account with your bank.
I bank here.
I bank with you.

If you're talking to a bank manager, it's OK to use "you" to refer to the bank.

So "In" doesn't work. "I am a customer at your bank" is it correct?

 

[emsr2d2]

So "In" doesn't work. Are you asking us or telling us?

Is "I am a customer at your bank" [strike]is it[/strike] correct?

If "in" worked, I would have included it in my list.

If you want to use "I am a customer ...", follow it with "of your bank". However, it's more natural to say "I'm one of your customers".

What do we need to say "who" or "whom" do you bank with?

 

[Tdol]

I would use Who do you bank with? You could ask With whom do you bank?, but this might be a bit formal for most speakers.

[strike]What[/strike] Do we need to say "Who do you bank with?" or "Whom do you bank with?"?

Note my corrections above. "What do we need to say?" is a standalone question. You can't follow it with a continuation of the sentence/question unless it's something like "What do we need to say if we want to ask someone for directions?" (that's just an example).

While you are still having problems with punctuation, I think you should lay out your questions differently, especially when you're asking us to choose between two options. I suggest that you phrase your questions like this in future:

Which of these two sentences/questions is correct?

1. Who do you bank with?
2. Whom do you bank with?

No, I don't have any problem. But few days back somebody asked me not to capitalise other words apart from the first word (except nouns).

 

[emsr2d2]

I didn't mention capitalisation. I said you were having problems with punctuation.
