I tried to cascade the issue to higher level and did ask to meet person in charge, but it is not allowed, only complain will be through mail !!!
BTW i start to post this complain through amny social media site, may be someone will listen. let C.
Its is not matter of the amount i lost or they will refund. but the more important that customer service is treating us behind a big wall, even i didn't receive a phone call from any supervisor for explanation, that is what make my very irritated.
