Well let me tell you something
Your money won't get lost anywhere if you do online transactions , there are regulatory bodies who monitor these systems and they are launched only after full testing.
In most of the cases it is due to users negeligence . Last time - Sum '09 my friend paid online and he paid twice with two names and the amount got deducted twice. After informing to IEI Kolkatta they had send him money return. While at the same time i paid the fees online without any trouble.
While doing online transactions here are few tips:
1) Check whether the site is not a fake site --> HTTP(No) or HTTPS(Yes), Lock icon below in status bar,
2) Avoid refreshing, clicking to go back or Alt + <- , disconnecting from session, it may cause the money to get deducted but it gets debited again after few days.
And remember to keep ur Security Updates to lates (AV, Browser, OS)
