While we're all for free press, it's worth realizing that Bittrust is an uncensored, anonymous feedback service that allows for all kinds of creative misrepresentations - whether it's to pad your own company's ranking or smear its competition. As an anecdote to this, while they have much to improve, it should be clear that Coinbase is no scam - and yet, there are countless Bittrust reviews claiming just that. Without a credible source, there is limited credibility (which, as a side note, is also why we're replying officially as Coinmama).
Regarding the matter at hand, Frodoe was able to provide identification and we can see that not only did we answer all emails we received (most within minutes), but can confirm that the money in question is currently being held by their bank, and will eventually be freed. Once resolved, I hope Frodoe will provide their perspective.
What you're saying is different from what your client is saying. According to him the money disappeared from the account. If the bank was holding the money the funds would remain locked on his account and show as pending. One of you two must be mistaken and I sincerely hope it's him.
Did someone recommend this exchange to you, frodoe7? It isn't even in the top 100 by coinmarketcap which says a lot about its popularity and volume. If you don't get your money back, be sure to leave a negative feedback wherever you can so that more people won't fall for this.
