Aggressive marketing from DarBerry.ru

Not so long ago, a startup Darberry.ru was being promoted at Habré. The idea seemed interesting and I decided to try the service in action. I registered and started receiving letters with promotional offers. The problem is that they were relevant only for Moscow, although I indicated Kharkov when registering. A few days later I got tired of receiving this spam and I decided to unsubscribe. But it was not there! First, I discovered that without asking me, I was assigned the city of Moscow without the possibility of changing it to another one or suspending the distribution. Secondly, I did not find an opportunity to unsubscribe and delete my account. I decided to write a letter to the creators of the service, where I politely asked me to unsubscribe me from the newsletter, but ignored my request - today I received another letter with an advertisement. I'd like to believe that all this is caused by a series of misunderstandings, and not done intentionally.
