"Be very careful with this company.
Like some other users, I found the service underwhelming. The company was unable to find a single date for me, so I assumed I would receive my money back. After all, the company proudly displays the following declarations on its website:
"A money back guarantee!"
"We guarantee to find you practical driving test cancellations or your money back!"
In the end, they refused to give me my money back, even though they were unable to find me a driving test (despite the statement above). I had found a date that was outside the date ranges I asked to company to search for, and took it because it was slightly better than what I had before. For the avoidance of doubt: they refused to reimburse me because I found an earlier test date for myself. Importantly, the date I found for myself was OUTSIDE of the dates I asked them to search for (which means I could not have prevented them from looking for the date I found because it was not within the scope of what I asked them to do).
The company has therefore
1. not provided an iota of value to me
2. taken my money, and,
3. refused a reimbursement, arguing that due to a technicality in their terms and conditions I wasn't entitled to one
I am baffled that their business model prioritises enforcing the small print (that contradicts what they loudly display on their website), rather than acknowledging the spirit of the understanding and pure logic that they simply weren't able to provide any value.
Although I have had a bad experience with their "guarantee", it is also worth pointing out questions about the business model here. The more popular the site becomes, the less effective it is likely to be because you are competing against too many other customers who want the same time slot. The probably of getting something within your desired range becomes small (indeed, I did not receive anything).
So to conclude, 1) the company goes against the spirit of the understanding that they will give your money back if they find nothing and 2) the probability of finding something goes down as users increase.
