How do I force social services and other organizations to delete my data?

Question

Social media

Good day everyone.
In the light of recent events in the legislation of the Russian Federation, I decided to clean up my accounts. When the tighter privacy settings, as well as the removal of individual blocks of information, were over, the turn of accounts came that had not been used for more than 3-5 years due to uselessness.
And then I came across a blank wall. Many sites do not provide for deleting a user. Technical support, when asked to delete my account along with contact details, either keeps silent or offers to “block” it. In the latter case, sadly, I continue to receive spam emails in my inbox, or receive SMS.
Recently, banks have contributed to this problem. Several banks that I used to work with, and with which I documentedly severed all relations, suddenly remembered my phone numbers and my mailbox, and began to send all sorts of dirty tricks to them.
Not so long ago I tried to get rid of an unused Euroset card. At first, technical support seems to have closed the account and the card. But after a while I received a promotional letter from them, and when I went to the site, I was surprised to find my personal account alive.
In connection with the above question: what are the ways to force companies to actually remove information about me from their databases. Well, or at least do not send me any bad luck by mail and phone.

Answer 1

If we are talking about Russian legal entities, then we can refer to the law "On Personal Data" N 152-FZ. If you read it carefully, you can not only refer to the law, but to its specific articles.

Answer 2

Yes, not really. I even tried to complain to the Federal Antimonopoly Service (Moscow) about the spam that is sent to me via SMS by generally left-wing companies that I have never dealt with - zero emotions.
If you don't have money for lawyers to sue each organization individually, then I sympathize with you.

Answer 3

“Everything that once leaked into the network leaked forever” I don’t remember the author.
In general, several of my friends maintain a separate personal mailbox, a mailbox for all sorts of spam mailings like comfort programs.
the same with ICQ and phone numbers, with Skype it is more difficult - all logins are searched for real data.
You will no longer be able to get drunk, even if you delete the query history in Google / Yandex, you are already included in the statistics and logs anyway.
