Really mad.

I cannot get the internet connected in my home today!
An IDIOT salesman lied to me that the internet speed is about 100mb/s and it would cost me about 13,000won per month. So, I ended the contract with KT even though it suggested me the price of about 15,000won. Today when the engineer set the internet, it was less than 85. Are you kidding me now? He said I asked the lower version which I didn't. I complained this to the salesman but he said he told me that the speed is not fully 100, less than 100 but it is quite well. What a liar he is!!!
