Expecting a prompt response / I expect za prompt response

[Tan Elaine]

This is not the first time I have purchased clothes from your outlet but this is the first time I have experienced a problem. Of course, I do understand that problems of this kind can happen from time to time. I, too, should have been a bit more careful while choosing the item. Right now, what I am hoping is that you will take measures to replace this faulty shirt with a good one. I can show you the receipt if it is necessary.

Expecting a prompt response,

Sincerely
James

Would it be better if the sentence in bold if I changed the words in bold to "I expect a prompt response"?

Thanks.

There's no need for such a rude demand when complaining for the first time.

Leave it out altogether, or say something more polite, like

'Hoping for a favourable reply'.
