I have had to contact Comcast customer service 7 times over the last couple years because of a recurring modem rental fee.....when I OWN MY OWN MODEM!!!! They promised the last 4 times it wouldn't happen anymore but it keeps happening. The worst part is they merely credit the amount they OVERCHARGED me and do not attempt to properly compensate me for this RECURRING headache! Not to mention, their prices are absurd because there is no real competition for them here!
