charges ?

hello ive been on this company for more than a year i started paying 30 $ for internet like 5 months ago i've been paying 80$ i think its too expensive it practically doubled the price and i don't even know why we use like 1/3 of the permitted data each month i don't need any telephone line because we have cell phones im not interested on tv so i'm  thinking of just cancelling since century lick offers 50mb for 29.99 as well
