Reading through the above there seems to be a general thread of lets have a moan - but slugman have you spoken to the Modular team?
When I dealt with Oxford the sales team were useless, but talk directly to the Modular Instructors and they will solve your problems.
I studied with Oxford, and once you got past the sales team the service was excellent. Slugman - You say you are registered with Oxford, so why are you still dealing with the sales team? As a registered student forget sales and go direct to the instructors. In my day the number was 01865 840 334 - I don't suppose its changed.
Good luck with the course
