Everything! I ordered my test 10 days before my arrival in the Uk. The test never arrived. I was only in the Uk Friday to Monday to visit my elderly mother: I spent a lot of my time waiting endlessly on phone in vain for Vivo to respond on telephone number but gave up. At the airport myself and another passenger who had also ordered a test from Vivo Clinic did not receive the test. Both in the same predicament we tried to explain at the boarding gate. I had done a NHS lateral flow test and had the result on my phone. We were both unable to board our flight. We intend to report Vivo clinic. It is scam!
