Complaint Review: dex media

A repesentative from dex media came into my business showed me an advertising format and i was hesitant , but she told me i had a grace period to change my mind well after not hearing from her or the company i had to contact them and they finally got in touch with me a presented me with a poor looking website and was horrible so i was not happy with being left in the dark and the way the company was run so i decided to take advantage of my grace period which i was told i had til the end of october and i tried to cancel and now im told i cant , what a nice scam so i called her and she said she's busy and basically has given me the cold shoulder,,,so now what do i do ......
