KT Communications Inc review: They got details and started to take money from my account 2

I recently called to KT Communications Inc. I was so angry that they pressed on hold and I waited 10 minutes, when they took 30 cents per minute. So, after the agent responded, he asked to provide the card details, so they would work further. Unfortunately, I trusted this agent and gave details, but after he got information, he hung up on me and I went to check my account, where I have found that they already took $30 from me. People, be aware and don’t give your details to these liars.
