It was mentioned somewhere by them that you could get one or two for free. I don't think however they've finalised when you'd be charged so while these issues are ongoing it may be free.
This is what I don't understand. I've never been charged for a declined transaction first of all. So I don't understand how that even happens. Then in the case where a terminal does a double transaction other banks would reverse the second usually immediately.
This whole issue doesn't make sense. Transactions aren't even supposed to be processed but just reserved. It's up to the merchant provider to then charge the transaction a day or two later.
I don't think it happens often.
But when it does happen, previously Tymes systems were quite good at automatically reversing it immediately, but they changed something that caused this frustration when it does happen. They probably have reason for what they are doing, but I think they have declined a bit in this aspect.
As with everything else, they are probably working on improving it also.
