During my "communication" with SONM, they showed repeated times they were not reading my emails. They finally tried to reply in the ANN thread with falsehoods and implicitly accusing me of some bad intention, while I was trying to talk for weeks and they only gained time saying they had a lot of emails and blah blah. They gave me tokens the moment they chose, manually processing my contribution nearly 5 hours after I sent the transactions, finally they gave me a worse exchange rate and wrong bonus. I published all the transactions, I even signed to prove ownership of the BTC address I contributed with, and they ignored for over a month saying there were "scam" attempts, when finally they came with a pathetic reply.
I confirm I had a similarly unpleasant experience with incorrect bonus calculations. First they asked to send our complaints to
bonus@sonm.io, yet ignored all emails for more than one month, while repeatedly promising all issues would be solved "within a few days".
In the end they denied any token difference on the unproven claim that they got the correct ETH/BTC conversion rate from Coinmarketcap. I asked them several times to prove their claim and disclose the exact calculations based on BTC transaction's timestamps, and show the history API they were using to get conversion rates one month back, but they never answered. That would be a chance to show their good faith and transparency, as any reputable and trustworthy business does, but they prefer instead to keep treating others like idiots and lack common basic respect for contributors...
It's not surprising that SNM price is still far below ICO's rate, despite the recent announcement that Binance is listing it: after all price is made by the market, and the market won't trust any business which behaves in such a shady and disgraceful way!
