I've talked with them for a trademark registration, first of all they will ask for money & will call you again & again until the money received after that they won't respond you properly. When i asked them to return my money, they are charging 20% deduction for the whole amount which is very huge. Even after getting agree on that, they are not refunding my money. Its been a month. Please never give any job/task to this company.
