I cancelled my line several years ago when I got tired of ATT "giving me special rates" for just a dial tone. When I forget to ask, they charge me double that amount on basic service so I have to call each time or else I pay the highest rate they can charge

The lowest rate they gave me was $10 for a dial tone, unlimited LOCAL calls.
When my bill comes, I have to ask for explanation on how my basic rate of $10 comes up to 22.xx on my statement and they tell me they have no control of all the federal and local tax charges. Fine. Just cancel my landline.
The best decision I've made was to shift to Magic Jack where I can still send/receive fax, make local and out of state calls, free. All for $20 per year. I can live with that.
