Ive ran into some issues with BinaryBlocks where ive paid them for 1 year of service for some of my customers (as stated in another post) but they are now "shut down" menaing im screwed for the money.
How recent does the cc charge have to be with visa for me to be able to charge it back? and is their an online form to do this? must i got into the bank? what kind of proof do i need? will the fact that their website says they were shutdown due to non-payment count as enough to get a refund?
The process is rather simple, however, you need to call your credit card company and tell them what happened. Keep in mind, that you need to have a "good reason" ready to tell them on why you want a chargeback. And that's pretty much it. You really shouldn't have any problems with this.
