A note to those who may have billing queries:
One point perhaps worth adding: it is most helpful in the case of querying
billing errors, if you have your info available. After all, this is the
catalyst for determining you have found an error and - importantly - the
overwhelmingly likely reason for the mistaken billing is the system not
having recognised/interprted a successful transaction. Hence, retrying
or lumping together a bunch to retry. This tends to mean the communication
back from card processor - the results of the previous transactions - were
incorrectly received or logged; hence possibly wrongly recorded. YOUR
records will be accurate. After all, they show what was charged. If there
is any doubt, and the transactions fall between the dates of the system
overhaul, then your records will supersede those on the Avalon system.
So do be honest and don't take advantage here!
