ESTAFA CASE against SM

hi! i have purchased a ti ket at smtickets.com. my credit card was charged but i did not receive confirmation message of my tickets.
i called smtickets.com and they just told me that it was unsuccessful. i explained to them that nothing online showed that it was a failed purchase. and thag in fact my card was charged. now the tickets are sold out.
wjat can i take against them regarding this?
i was demanding them that they provide the tickets that i have reserved and paid for.
and thay their system glitch is not my fault. hoping to hear from you. thanks

I don't think this will qualify as estafa.

what case can i take against them

This happened to me before while buying my plane ticket online. It took 30 days before I was able to get back the money (debit card). The problem is that there are lots of things to consider with system glitch. It may be their front end server, their service provider, your service provider, network (yours/the other party). Any drop/time out caused by these can cancel the verification process. There is nothing you can do about it since this is a known issue when buying stuff online. The only thing you can do is to file a dispute to your credit card company/bank. They will know if the transaction is posted or not. It may be charged but not posted. That's all about it.

thank you
