The funny thing is that the day when the technician came, he forgot to bring the modem (lucky that I have my own). He promised me to deliver it to me after his CNY leave which is yesterday. Again I never put my hope that high which is correct. He didn't deliver the modem.
But today he called me and sent me the modem. Oh my! Imagine I let him go before CNY the other day. It will be nightmare for me for not having an internet line for a whole.
