I bought a second user AIO computer online, It arrived and I tried to enable the touchcreen option that was advertised. I couldn't it as there was no option.. I requested a return under distance selling and they have refused. Lambdatek say touchscreen optional mean it does not have a tocuhscreen. I disagree NON TOUCHSCREEN means no touchscreen. Lambaatek were selling me a specific machine, there was no "option" they could sell me for a touchscreen so why tell me all about the features of a touchscreen? I've told I can have a partial refund, then no refund. I've had argumentative emails from two people called Sutan and Gabriel in the returns dept. maybe they think The Consumer Contracts (formerly Distance Selling) regulations do not apply to them. I am fuming!!!!!!!!!!! AVOID LIKE THE PLAGUE.
