The service was expensive, and whilst the test packs were delivered on time, the process for sending and receiving the test results was extremely poor. With Royal Mail as the mechanism to send the completed test it could take 72 hours for the test to be received by the lab. After that it could take up to 72 hrs to get a result. My wife never got her Day 2 result. When we complained we were told that their Customer Service was a great team; as customers we should be the judge of that and it our view the whole service fell well short of what i would have expected for that cost.
