Customer not ready to send free of goods back But he wants money back for damaged stock

Question

Dear sd Experts please tell me How To Achieve In SAP
Customer : 120000
Company: AAA
AAA Company offered if customer purchased Material ZZZ  For 100 qnty They will Give Free of goods Material XXX 15 For Diwali
: ex: Now customer Purchased 100 qnty and he got 15 Free of goods from the company Now This scenario ok Imagine stock reached just one day before DIWALI  suddenly Customer Found some damaged stock Like 10 Items
now he wants to back the stock  and he doesn't want the same material 10 Items  (zzz) He wants only Money
because Once DIWALI Completed he cant sell the products he will be in loss ( i am giving just example to understand)
so he wants money back .....................For 10 Qnty
But he is not ready To Give back Free of goods Back (XXX) Because He purchased the stock From the company is giving free goods thats way
Yes it is correct point From the customer side because every customer will think like this only no wrong with him ...
Now coming to Company issue .... Company everything calculated material cost and finally decided That 100 Material ZZZ We can give XXX 15 Material As a free of Goods here no loss and no profit 
But if customer Is asking Money back for Damaged stock and he doesn't want To give free of goods back ,,, So here from company point of view some loss will be generating definitely..100 %  so how we will proceed with FI @MM IN SAP
Because I think another option plz guide me
Thanks a lot

Dear Venu,
As i understood On a purchase of 100 TVs--10 DVD players are free(may be 10+1 offer)
Now after receiving customer found 10TVs damaged
(only TVs got damaged--not the free good DVD players)
So he returned those damaged 10 TVs back to Business and he dont want to take this new 10 TVs based on his sales after his seasonal experiences.
So now the adjustment can happen in the following ways:
(solely depends on your understanding with your customer)
1.Adjust the total amount only for 90 TVs(you can use credit memo else invoice correction request)
2.here the question comes is for 90 TVs only 9 DVDs are free--(here again you can do in two ways charge the customer by a debit memo for additional one piece of DVD player   or   ask the customer to return that one DVD player)
Hope this helps.
Very Important note:
I just saw somebody asking you to correct your punctuation and there is a like given by Our senior and respected member JP. we have to understand one thing here--always we  need to take these comments as positive manner(recently our respected moderator JP cautioned me  too through a direct message asking to correct my diction and some spelling mistakes--which i might be doing without any intention)
Remember one thing in life--- all of our respected senior members are here to help us whenever we are facing career threatening issues--even though they dont know us personally --they are helping us & we come out with victory and smiley faces from all these issues--we should respect their comments and say thanks to the people who is correcting you at your career.
To Respected JP: sir--i think you might have observed the change in my approach too
(like ""me too"" at your message)
whenever i am crossing-- requesting you again to correct me.
sorry to give this pain again to you sir.
