This case will get my guilty vote BUT... I have to post a comment for future readers...
1- They never send me the E-book I asked for to learn the Forex trade -- You are a new Forex trader?
2- The never try to teach me how trade -- Was this a condition of opening the account? Most brokers offer some (albeit generic) training on their website but you assume the risk when you open a live account and post funds to it.
3- They promised to give a bonus (30 to 50%) but they never did -- Was this "promise" in writing with the account forms you signed? Very often these "bonuses" come with many strings and restrictions.
4- they said they are there for 24 hours support but they were never been there when needed -- How was this verified before opening the account?
5- they used to withdraw money from my credit cards without my permission -- This appears to be the most egregious infraction of the list. Read your account documents VERY closely to be sure you didn't unwittingly give them permission in the "fine print"
6- They opened some unsuccessful trades without my permission -- Again, a serious infraction if this is as stated. Are you sure these were original opening position trades (not closing trades due to margin requirements)?
7- They held my money and did not let me deposit it back to my credit cards -- I assume you are referring here to your inability to withdrawal funds.
8- Try to contact them by phone, I was always directed to an extension where no one answer or to my account manager will call me back -- This is certainly a RED flag
9- My account manager never answered my mail when I needed his advise for important trade or when asking him to unlock my account to send money back to my cards -- ditto #8
10- Have sent 2 dispute cases to my HSBC bank in Middle East & MBNA bank in Canada -- supporting evidence but not directly relevant to judgement of UFXMarkets
New traders unfortunately are unaware of forums like FPA and therefore miss the most important lesson in starting to trade (Forex, Futures, Options, or Stocks)... that is to do your due diligence on ANY broker BEFORE sending money to an account. I did full due diligence on TD Ameritrade before funding my account and they are an internationally known brokerage. I would do the same for ANY institution that will potentially hold my money for whatever reason.
Caveat Emptor: Unfortunately and especially these days, fiduciary (money related) institutions are NOT in business to serve and protect YOUR interests. They exist to make money for their owners PERIOD! You must do your homework and seek out the dirty laundry BEFORE getting into bed with them.
