LG Electronics — regarding offer for lg mobile

Good evening sir

I have purchased my lg v30.
But now less than a month after i purchased you have started another offer. Giving free bluetooth headset as well as wireless charger. Which is very unfair.
I would like to request to get an bluetooth headset as i have purchased at same price and before and that too i am a regular buyer of lg mobiles...
Please find the below attachment for the invoice.
I kindly request you to provide us the bluetooth headset... As we have purchase for same price and within few days only.. If you are giving such a huge offer... Its very unfair.. I feel..
I kindly request you to consider this and provide the same.
I kindly request you to help in this regard
