I purchased 20 aged Gmail accounts from this provider. Only 10 accounts worked, and the rest were disabled by Google. It happens, I understand.
He replaced the disabled accounts within 2 days, but then none of the replacements worked. They were also disabled.
I then discovered that the original 10 that worked in the first round also became disabled. I saw that on at least 1 of these accounts, someone else logged in using the original recovery phone number and tried to re-gain access. I suspect this happened to more of the accounts that got disabled.
Ultimately, none of the emails I purchased worked.
The provider explained that the accounts can only be able to replaced if they don't work upon the first login, so none of the original 10 could be replaced.
The provider responds relatively quickly and provides instructions on how to log into the accounts and change the passwords/recovery mails.
Currently pending an answer to a refund request for half of the order. No hard feelings, just sharing my experience. Thank you
