(something) has been (done)

This kind of sentence is called a "passive" sentence. You use "have been ___ed" when you don't want to say who did something because you're trying to hide it, or just because it's not important.

If someone asks about the dishes in the dishwasher:

Have these been run?

...the speaker asks "Have these been run" instead of "Did you run these?" because it's not important who ran the dishes. It could be any member of the family.

In the example:

Yes, I just wanted to verify that my payment has been received?

...the speaker doesn't know exactly who receives the payments. All that's important is that the correct person or department received it.

I wanted to (do something)

A very polite way to explain why you're doing something is "I wanted to ___". For example:

Hi Jen. I wanted to see if you'd like to come out with Emma and I and some friends of ours to a show next week.

Yes, I just wanted to verify that my payment has been received?

Some phrases that can be used after "wanted" include:

I wanted to ask...

I wanted to tell you...

I wanted to check to see if...

I wanted to remind you that...

I wanted to let you know that...

I wanted to find out whether...

Note that this is in past tense: you say "I wanted to ___" instead of "I want to ___". There's no grammatical reason for making it past tense; it just makes your sentence sound more polite. When you say it this way, it sounds like an explanation for why you're calling, why you're visiting, etc. 

just (do something)

You use this phrase when the action you're describing seems easy, simple, fast, unimportant, or unexciting:

I just googled "new york florist" and that was the first shop that came up, so I called them.

A: What did you do this weekend?

B: I just sat at home and watched T.V.

receive (something)

To "receive" something basically means to get it from someone.

We received over a hundred submissions.

The word "receive" is pretty formal. It's used in official documents or in business communication. In normal conversation, "get" is more common:

We got over a hundred submissions.

"Receive" is often used in a pair with the word "give" - there's a famous saying "It's better to give than to receive."

Yes, (sentence)

This is a polite way to start a telephone conversation with a business when you don't know the person you're talking to. You speak this way when:

• You call customer support.
• You call for someone at work, but someone else answers.
• You call to make an appointment with a doctor, dentist, hair stylist, etc.

verify that (clause)

To "verify" that something is true means to make sure. "Verify" is a more formal word and usually used in business situations where you don't know the person you're talking to.

You verify "that ___". You can also replace the clause with a word like "something":

Can I just verify something?

?

Even though the example above is not formed as a question, it would probably be spoken with the intonation of a question. When you're asking a question, your voice gets higher (in pitch) at the end of the sentence.
