This is why people recommend Mila (not me, because I've never been to Kharkiv and haven't used her services, although we have corresponded briefly in the past). She listens to people's concerns, takes note, and does something about it to make her service better. She's also the only person in her trade (except maybe Stirlitz? can't recall) who has actually apologised on this forum for something which appears to have arisen simply from a lack of communication, rather than as an outright attempt to rip people off (e.g. Anastasiadate, A Foreign Affair, nearly every other agency in the FSU...).
That she's prepared to do this in public, rather than just send the aggrieved person a PM, is a huge tick in my book.
+1. The relationship between a guy and a matchmaker is fraught with issues if there's no open dialogue. I don't think it's possible to please 100% of guys 100% of the time. I've established a friendship with Mila and her husband over the years, so I think it's safe to say we can be honest with each other about things - whether it be me having an issue with the service or cost, or her having an issue about how I may have conducted myself with women or on a date. If some guys don't have the ability to use what's between their ears or aren't able to openly communicate, they'll struggle in Ukraine full-stop. Who can't use Uber or Tinder in this day and age? To spend 2 days just walking around in a city like Kharkov with beautiful women and numerous methods to meet them is a waste if you really want to meet someone.
Unless something changes, I probably won't use Mila's services in Kharkov again, but we've become friends. I met a great lady in the summer because of her, sadly things just didn't work out. I've become pretty independent now in Ukraine and I like to manage my own schedule and choose my own type of lady when I'm there. If it's your first visit, I wouldn't talk you out of it. Like everything, different things work for different people and YMMV.
