I'm really so angry that I won't even use the initial
 consonant. I'm not
 exaggerating at all. I was tempted and made a same-day reservation last Thursday and paid 800,000 won, which is 10% of the square jaw of 800. I had it extracted, had an x-ray taken, and had about three types of tests like brain waves.)
 But as I kept thinking about it, I realized that there was no need to have this major surgery.

So, I told the manager that I wanted to cancel today, and
 the manager immediately changed his attitude and said he was sorry, but
 1. he could only refund 80% of the reservation deposit, and
 2. since the tests done at that time were worth 300,000 won,
 he could only refund the total minus 460,000 won.
 
Well, I was going to do that because I knew about number 1 (even because I was asked first), but I was so dumbfounded that I couldn't say anything about number 2. There is no word on how much the pre-surgery test will cost, but here it is.

The manager said that he would call the Fair Trade Commission and call them again, saying that we were confident, but does this really make sense?
