Purchaser demanding a refund one month after purchase

Q: I advertised a hunting scope on an online platform. In the description I wrote the name and the condition of the scope been fair condition. An individual messaged and on 20 March 2024 and I sold the hunting scope to this individual. 

On 25 March he confirmed receiving the scope and was happy. A month later he messaged saying the scope is not working and demanding a refund. I said its one month later and I can't do anything as its a second hand item and was bought and sold as second hand goods. Then he demands a receipt for the item which could not be provided as its second hand goods with no warranty. 

Apparently he wanted the receipt as the company of this scope has a lifetime warranty which he could claim if he had an original receipt which could not be provided. The scope was sold for R2000 which was in fair condition. All pictures of the scope was shown to the individual before purchasing. A scope brand new is about 8 to R10000. Its been around 5 months since the purchase. What do I do in this situation?

Is the body of the deceased pure or impure?

Q: Is the body of the deceased, before giving ghusl, regarded as paak or napaak i.e. is the deceased body treated like a person in the state of hadath (i.e. if the water which touches the deceased’s body comes on to the person giving ghusl, the water will not be regarded as napaak and impure) or is the actual body of the deceased treated as something impure like an animal which dies a natural death is treated as impure (i.e. if the water which touches the deceased’s body comes on to the person giving ghusl, the water will be regarded as napaak and the person will have to cleanse his body of that water)?
