Evetech is the worst electronic supplier

I bought 2 laptops after mine was ******. It is now 7 days and not one laptop is working. I only get blue 'death' screens. They don't help me and don't want exchange for new ones. I cannot do my work and are losing income. I am now also going to contact the HP international as well as Lenovo. It can't be an accident that 2 different makes of laptops react the same way.... Don't ever buy from Evetech. The don't know what they are doing and the customer service is not existent..
