Whey do these people have a monopoly on Covid-19 tests at Heathrow? The staff at the Terminal 3 facility are security thugs who are working for minimum wage. ABSOLUTELY HORRIBLE TO DEAL WITH....... They do not accept cash or credit card and insist on registering for an APP and then creating an account and then paying for the service. ABSOLUTELY FAULTY TOWERS SCALE OF BUCK PASSING. ABSOLUELTY THE WORST COMPANY IN THE WORLD TO DEAL WITH. No phone number, no nothing.
