DSL speeds

I currently pay for 50mbps package, but i rarely get over 4mbps download and 115kbs upload. this is p*ssing me off. Normally i’m never a disgruntled consumer, but when i pay $80 a month for internet, when i don’t even get the speeds of the 10mbps package i get angry. I’m sick of it. there’s no other provider in my town, and fiber optic hasn’t made its way to my side of town. i’ve been an at&t customer for 15 years, but i’m about ready to shut off all internet and change my phone provider as well.
