Odnoklassniki.ru in continuation

Good day. I know that many have already written and read about all these social networks. And everyone already understood that it’s not easy to “leave” them (delete your account).
But the problem here is durga.
Everyone knows that the authorization of the user goes to his email address and password, which can be changed if desired in personal settings.

But recently, for technical reasons, I had to just temporarily change my email address on the site, and sit under the new one.
That's where the problems started.
After a while I had to return to the old email address, and I found that the system gives an error, and writes that this email (that is, my first one is already in use by the system). Ie in the database in the logs there is a mention of my past.

First of all, I wrote to the odnoklassnikov support service and started to get greedy. I waited a day, two, three, but there was no sense to it.
')
After 4 days, I repeated the procedure with all the old and new data and asked for quicker help.
But to my surprise, I did not even want to respond to my letter.
Even some auto-bot did not answer.

The result is one. I've been trying to return to my old email address for a week now, and I can't do it.

So I think, really no one wants to work?

Sincerely, Sergey.
