well, lingloong case reminds me a similar case which i just started business 2 - 3 years ago
1. a buyer bought a mobo from me and insists request poslaju due to his place at klang dunno which part say private courier company is lousy.
2. payment made i courier the items.
3. poslaju sent late, online tracking system sucks
4. customer call and F words me upside down and accuse me conning him
5. politely apologize and give him a friendly reminder he is the one insists using poslaju, as well tell him when the items reach do courier back to me which i'll bear all the cost since you are so not satisfied.
6. items arrive after 10 working days (as i include saturday is a working day), customer call me up early in the morning not for apologize for his rudeness but tell me "lain kali jangan con tau, i sumpah kan bunuh engkau". (early in the morning putih putih kena for nth)

so, do it still "customer always right" ? enlight me
p/s: is a lyn forumer
