update:

so last night i met up with him and he return my w810i and made a payment of RM65 coz he said at that point he didnt have enough cash..
nice enough he said he would keep in touch for further transactions of the refund

basically at this point..

1. i'm at a lost of RM 100
2. i did not get any items
3. petrol cost all oso nvr count (that one i dun wanna count)

so basically RM 100 lost to him for nothing in return
