10. Sprint

Body count: 14,500

The third largest cellular provider announced 8,000 job cutbacks in 2009 to reduce internal and labor costs by $1.2 billion annually. Its merger with mobile walkie-talkie specialists Nextel opened up another wound leading to more budget cuts and a subscriber plunge of 100,000 reportedly due to bad customer service and dropped calls. Sprint would place its focus on increasing customer satisfaction and close 27 call centers stating service improvements decreased call volume. That just doesn't add up.
