I went through the normal process, was matched and given a challenge to collect 15,000 status miles on Turkish Airlines International flights. I met the challenge during the first membership year, but they mysteriously downgraded me to Classic Plus at the end of the year. I sent them several complaints outlining the fact that I met their challenge on the type of flights they required and within the one year challenge period.
They just ignored my complaints and never responded.
It is a big scam. Don’t do it.
