Has your bank been able to help in your case? I was on hold for more than 1 hour with TD and they couldn't do anything, the person just said i am looking for information and never put me back on line, I had to hang up after 1 hour to attend to my work.
I am pretty sure something is up with the banks because I did see the message on the machine which said transaction declined or something, so seems like bank didn't let the transaction go through but eventually they let the payment go, so I wouldn't blame BLS because the person on counter wasn't trying to hide any message and I am pretty sure BLS aren't that tech savvy to make the debit machines show fault messages, so seems like a banks fault. However, the thing that sucks is that the money is stuck now and for a family application its not a small amount.
