Is "retention" correct?

[Polyester]

Please stop the tee for any rentention program, only one year additional warranty.

Is it correct?

 

[emsr2d2]

Are you sure you meant "tee"?

 

[Polyester]

I meant the messages as follow:
"Please stop keeping the tee for extra gift to customer, we've given a year warranty instead."

Please check. Thank you!

By 'tee', do you mean T-shirt?

 

[Polyester]

Yes. Rover_KE
Can you please tell me my first post #1 is the sentence correctly?

 

[emsr2d2]

I'm trying to imagine in what industry a customer's free gifts could be either a T-shirt or a year's warranty. However, I think you mean something like:

Please stop giving customers T-shirts as a free gift; we're giving them a year's free warranty instead.

 

[Polyester]

emsr2d2, you give me a good example, I appreciate your help.
But, can you please tell me both sentences are making sense or correctly to use as follow?
1. Please stop the tee for any rentention program, only one year additional warranty.
2. Please stop keeping the tee for extra gift to customer, we've given a year warranty instead.

 

[emsr2d2]

Neither of your sentences is correct.

Dear all teacher here,
I don't appreciate your help, because all teachers here are talking about your sentences incorrect. But, they don't give more details about which parts are incorrect, or which parts are needed to be revised.
I say it again, all teachers here are using a sentence like "Neither of your sentences is correct."
This is useless, it's also not improving our English.

My suggestion is "please all teachers here are giving the reason why is it incorrect to all posters". This is helping us to learn the language.

If you don't like my advice, ok , you can attack me here.

...and the same goes for me, too.

But, they don't give more details about which parts are incorrect, or which parts are needed to be revised.

For details, please look up in dictionaries the words used in your sentences.
I often consult dictionaries/grammar sites before asking a question here.
