problems with @booster

After having had some good experience with the Hive account@booster voting bot I got finally burned by him when he went offline.

Not aware that he was offline for good I sent 10 steem and never got them back.

This happend several weeks ago and I tried to comment on his massages and spam-mailed him with SBD transactions.. no reaction so far.

As I conduct an experiment about the economics of payed votes I rally want to know if this is intentional or just a major case of gross negligence and chaos... instead of just writing off the 10 steem..
( I still hope this was non intentional as I can not imagine someone organizing festivals ( Hive account@fyrstikken ) and campaigning to become a witness ( Hive account@fyrst-wittness ) ripping off people in the very same eco system he wants to help to develop! But
anyways ... if you offer such payed services I am 100% convinced you have to take care of such things)

So what might be the best way to get his attention to sort out this trouble and to know about his intentions?

Hmm...

using the very same upvote bot and betting on him actually reading what he is upvoting.. and if you do so Hive account@booster.. thank you for sending me my 10 steem back but please also look at your account as there are many other users with exactly the same problem.

Kind regards,
