I use the Migs Mastercard module on my site with Bendigo bank. I've had this for 3 years now working mostly fine.
Recently (and this did happen a few times awhile ago) some transactions are completed with money sent to my account but the customer gets a timeout error when being re-directed to the site. The order is not completed but I have their money.
It doesn't happen to everybody. In fact its a small but very frustrating handful.
The migs support crew say the transaction was completed and correct code sent back to my site.
My host says its the bank or the software.
Could it be the software?
I use version 1.3.6.

Any help would be appreciated.
