Okay so I've booked a test and changes the date twice. I now get a message saying that I can change it only one more time. If I need to change it again, can i just cancel the booking and re-book another time, will I lose the fee?
nope, you'll get your money back so long as youve given enough notice (i think it's about 5 days)
As long as it's 5 days or more before the actual test, they'll refund the fee.
It's 3 working days, not including the day of the test or the day of cancellation. A working day can include a saturday.
If you change your booking more than 3 times it locks your account and you get a message saying that you've made too many changes. How would one go about finding an earlier date in this situation? Would you have to cancel your existing test, with the risk of losing that date and re-book in the hope that there is an earlier date?
