Dell - In 2006, Dell acknowledged that it had problems with customer service, including transfers of more than 45% of calls and long wait-times. Dell's blog detailed the response:'We’re spending more than a $100 million — and a lot of blood, sweat and tears of talented people — to fix this.' Later in the year, the company increased its spending on customer service to $150 million. Some commentators have criticized Dell for employing vertical tying (a form of anti-competitive practice) by using non-standard components exclusively manufactured by Dell in their products — in particular their non-ATX power supplies, non-ATX motherboards, and non-standard connectors joining the power supply to the motherboard.
