It's NOT complaining, It's recommendation how they can do better them service.
I have a Mistertango account and I am very satisfied with it. Yes, there are fees and yes there are deductions after trading bitcoins on their internal exchange but one should not forget that they have staff salaries to pay... IT, utility bills, cost of leasing their company offices in Vilnius, and many other costs.
They offer one of the last few options on this planet for an IBAN account which allows BTC deposits. And a free MasterCard on top of that!
It's almost like they are donating their products and services so stop complaining.
