I purchased a PCR test to travel abroad. This was posted Wednesday 11th August at 8.30am in a priority postbox. This was just within the required 72hrs as our outward plane journey departed at 7.45am on Saturday 14th August. The test was collected that day and should have arrived at the lab within 24hrs as per Dante's guidance. Also from Dante's information the test would then be processed within 24hrs. This would have meant a result Friday 13th August, in adequate time for our outward flight. As it happens there was no result until we were in the air on Saturday 14th August, by which time it was too late. I tried to get in contact on the Friday but the reply was an automated "we are busy" email. I used this service as it was supposed to be efficient and timings work out nicely. As it happens I had to arrange a last minute test on Friday 13th, causing a lot of time, unnecessary stress and expense. This service fell short of what Dante committed and in the end was totally unnecessary as we had to go elsewhere to get the required result. Not worth the uncertainty and stress. Not fit for purpose.
