so this was how it went i lent my racquet to my friend, he was playing doubles with his partner. my opponent lifted the shuttle straight towards my friend, my friend smashed the bird, but his partner backhanded it (his partner is an idiot). I witnessed the whole thing and his partner was at fault, as a result, my racquet was completely destroyed. His partner is not willing to pay me back for the racquet , what should i do? how do we deal with lowlives like these?
