This is the second scam accusation I've seen against coinswitch in the past week or so, and my guess is that there's something fishy going on there.  Does coinswitch have an account on the forum?  I didn't find a link in the last thread I looked at.  Tagging them probably wouldn't help anyone get their funds back, but at least it would be a warning.

I do still have a Coinomi wallet (though I don't use it anymore) and I have noticed that they're affiliated in some way with coinswitch, as there's an option for instant trades within the wallet, with Changelly and Totle Swap (whatever the hell that is) as well.  Coinomi ought to think twice about offering swaps through coinswitch, because it does look like these are legitimate scams and they're not for small amounts either.

Sorry for your experience with these jokers, OP.  I had a problem with Changelly a while back and I know how frustrating it is trying to deal with companies that you really don't know that much about.
