i'm here not to help TS nor the seller, i just look at the right ones according to my own opinion,

the seller claim that he bought it RM150 ori from LYN member, but the fact shows that:

he actually bought the DS3 from another LYN seller only for RM90 as we could see he mention himself on the pic above.
this is the first lie i could clearly see from the seller, and it's definitely wrong to lie in the first place. (lie is always the beginning of CON case)

if he being honest, saying that he bought his DS3 from LYN for RM90 from the start and dunno that it's a fake controller, then it's understandable.
even TS could have time to think first before buying it from the seller. but the fact didn't show that.

i could see TS offered solution by asking refund with RM20 compensation, i think this might be a good solution to sort this mistake out.
seller can even get RM20 for free. but yet, he is not cooperating well with TS and complain in a rude way. as shown below:

from my side and for the best of other LYN members, i request MOD to consider looking through this case,
and could consider to put a dispute tag for the particular seller as of the case hasn't been settled yet.
because, seller seems rather ignorant about this,
and this is not good for other LYN members who will probably deal with him in the future, without knowing what kind of seller he is.

hope he can respond regarding this case, and provides a peace solution with TS at the end.
