They got back to me - they don't know what's going on.
I gave them the MG reference #, the amount paid, etc, in my support request / ticket.
And what do they do? They ask me for that info again. So now we have two support tickets, and above info mentioned 4 times.
I'm sorry that you are having issues with ZipZap support. I would suggest you are patient and work with them to continue to troubleshoot your issue.
