Yes someone who takes a few months to repair a miner and sends it back fixed and hashing is forsure a scam or equal to a scammer.
Folks are complaining about you not replying them for months, let alone send them a fixed miner, if my miner sits at your place for months which could turn into years, how is different from sending it to a scammer who stops responding to my email? In both cases the miner's is unknown, I did not claim that you are a scammer, my statement was clear, I am not responsible for any misundersanding on your behalf.
Some of our servers are in Ukraine and are currently down so we cannot respond. (This only refers to anyone that has tried to contact us in the last few weeks.)
So your mail server as well as your phone service are located in Ukraine? Ok.
Anyway, nothing against your company really, but honestly, why take more work than you can finish? Maybe hire someone to respond to the emails and pick up the phone? I mean eventually people will start calling you scam, and then you can't fix what has been broken.
Good luck.
