This exactly happened to me when purchasing an Amazon gift card. Amazon removed the balance from the gift card because the purchaser claimed the purchase was fraudulent, and I had to go back and forth with Purse.IO's slow and bumbling customer support over and over and over to get my btc refunded, which needless to say was incredibly frustrating. Thank goodness I did finally get my refund for a worthless Amazon gift card with no balance. So they aren't entirely inept, but goodness that was a pain in the neck.

One thing I want to mention is that Purse.IO reuses the same deposit address, which is bad  :

"When recycling is bad

Perhaps they’ll have to agree to disagree, but there’s another issue at stake: reused bitcoin addresses.

Many sites that add material into the block chain, like SatoshiDice, reuse bitcoin addresses, and many developers, Dashjr and Maxwell included, consider this to be a bad thing. After all, reused addresses were what allowed Dashjr to block certain sites.

If an organisation or individual continually reuses a bitcoin address, then it makes them more easily identifiable on the network, and also makes it easier to identify people transacting with them.

That can lead to all kinds of problems, Maxwell warns, including censorship. After all, that’s how Dashjr identified the sites to blacklist in the first place.

If address reuse proliferates among bitcoiners, then censorship by patches like Dashjr’s will be the least of their worries, warns Maxwell.

He explained:

    “If people use bitcoin in a lazy, easily censorable way where they are reusing addresses – which were always intended to be one-time in the design of the system – then this creates a serious systemic risk in that someone might try to order nodes, developers, and/or miners to censor the system.”"
