A recent problem with the sandbox accounts creation when using US as the country was resulting in an error, in the meantime when the issue wasnt fixed i tried creating different sandbox accounts with Brazil & Australia as the country which resulted in success, but after fixing the issue now i cannot delete those accounts that i created with Brazil and Australia. it throws the following error when i attempt to delete them by selecting them via radio button
Something went wrong. One or more sandbox accounts could not be deleted. Try again.
