I have heard some complaints that some people

made on steemit that they paid a bot to upvote

their post but the bots did not upvote their posts
and they are getting frustrated,but sometimes

each bots do have their own features and how

they operate,some bots upvotes at a particular time of a day and if you buy upvotes from such

bots it means you will have to wait for the right

time when they do upvote posts,if the bots do not

work such way and you did not get upvotes then

maybe you should not contact their owners through their discord channel or their contact

details which you have...
