Cloak and dagger type shiat. And it’s Bulgarian.....or Belgium......so more intriguery.
Don’t know what you emailed them but in light of their reply...or lack of....I’d go on the offensive and hit them back with a profanity laced tirade directed at their nationality, location, physical appearance, hygiene, moms loose morals and would finish it off by calling them idgits.
Unless your email was of a religious nature....in which case I’d omit any hygiene barbs....but leave the stuff about their mom in it.
And don’t forget to call them idgits.
