I failed my test on 18th/April/2017 and booked a test on 10th/June/2017. But after 3 days of using this service, they found a test for me on 5th/May/2017 (Only 13 days between the two tests, Wow !!). This service is amazing, very reliable and very cheap. I recommend everyone who failed his test and wants to redo the test ASAP to use this service; they'll find a test for the day and time range you specify. I used the premium service (they check the DVLA website every 5 minutes for cancellations!!!). I changed the settings to Automatically book the test for the time I specified. And guess what!! I woke up on 23/April/2017 and found an email from DVAL telling me that my test time has been changed (what a great news!). The beauty of the service is that you can use it as many times as you wish with only one payment (no matters how many times you fail). Definitely 5 stars and will keep using it every time I fail (god forbid!).
