I am really disappointed and very unsatisfied with the service I received.
I applied and paid for an express visa appointment, which they advertised to take 3-4 working days. It turned out to be just a marketing trick. 25 days later I didn't have my appointment booked. In addition, they never gave me any update until I asked about it. They just kept telling me that the appointment would be confirmed soon, which never happened. Eventually, when there wasn't enough time to get my visa before my flight, I asked for a full refund as the service wasn't delivered. They refused and offered me only half of the fee I paid. I spoke to a Citizen Advice and they told me this is a breach of a common law. However they seem to not care about it. This is the worst service I ever experienced. I don't recommend this agency.
