I think it is current limitation of transaction over internet.
The big companies can do what ever they like,means even if they are wrong there is always danger of getting reverse action and sometimes even being fine through we have done nothing wrong.
TAKE A LEGAL ACTION,is always eaiser said than done especially against big companies,in cross country matters and in mirco transaction.
The whole transaction may be of 100$ here but even hiring a good lawyer ,getting all the things and time will cost more than $1000.
so that is just advice for advice.
Bigger companies,any how will have lawyers on salary ready to defend even if they are wrong,so at personal level it is not possible to do those things.
At in many countries if things gets legal,there are not police officers who understands the actual matter,so u may be treat like criminal actually.
I said limitation as ,it happended to me some years back
I outsourced a task of 140$,paid through paypal,i even asked my lawyers about the agreement.She said it will take around 100-200$ to prepare an agreement that could be legally produced in court as proof,as it was cross country transaction.
so it was to cost me more than 350 with that,plus one never feels she will be scamed when she gives the task.
so i didnt made any documents and believe them.
later they scammed me,gave me nothing and when i asked them about the task ,they said if i keep on asking about the work and post any thing any where,they will file a case against me in their country.
As,with out any proof now,i could do nothing.
so to be frank in most of the cases online transaction has been all about luck ,even in ecommerce,many vendor just pay shipping charges and lose the product as well...
so feels like somebody need to do something for the betterment and international proof of the transaction and task
