Thanks for your advice guys.
I have sent the following email to Blockchain:
Hi Mike,
.......
I see you very politely write a letter in support of Blockchain.com.
I also started to communicate with them politely, but when I went to the 5th or 6th useless and stupid answer, my nerves could not stand it, my letters became rude and demanding.
In my opinion, the support team has a special technology to write the first 5-7 answers about nothing at all and do nothing. Perhaps the problem applicant will get tired of this and he himself will be left behind forever with his problem. Especially when he has a couple of dollars, or a couple of tens of dollars in his account.
