I posted an English-teaching ad on 58-Tongcheng. Then I started to get texts from someone who offers TESOL program. I just ignored it. But I kept getting this message on daily basis. It is so annoying. Then today I sent a text back to this contact, just saying:" Can you please stop sending me ad text, if I get one more, I will report your message as spam text." Then I got an answer like this:" Don't be a loser, alright." I was like, what is that, you guys illegally collected cell numbers and send out ad everyday, how annoying is that?! Then I called back, a woman was yelling at me:"What the fuck is your problem..." then gave no time for me to talk, hung off.. The last text I got is :" Deal with it,bitch." I NEVER experienced something nasty like this before.. I googled this phone number, found out it is the American TESOL Institution, Kunming Location.. AN EDUCATIONAL ORGANIZATION, seriously?! No kidding!!! And they supposed to teach people how to speak proper English, and this is how they talk. I deleted my ad on 58-Tongcheng. So here, just let you guys know, if you are going to post ad on 58-Tongcheng, be prepared to receive all kinds of ad phone calls and all kinds of spam texts. If you received it, remember: JUST IGNORE IT, delete it, do not get back to that person. Maybe the best way is just to read the spam,rather than to get those so-called TESOL teachers to call you names.. :(
