Shocking service ….avoid at all costs.Booked PCR tests guaranteed results next day 1159 pm .Time came and went no results , no response to e mails.Flights booked results arrived 11hours after promised time , 1 hour after check in for long haul flight ! Luckily we were able to book a rapid PCR at the airport result back in 1hour .Had we not done this we would have missed our flights . Not one apology or attempt to rectify our concerns £375 wasted but have contacted my credit card company as Vivo breached their guarantee .They also advised on their phone recording they use their own clinic for testing . They actually use randox labs much better to go direct through them half the cost also
