Cochran Landscape Managment, INC. Charge me without doing work easley South Carolina

No service was performed. My credit card was charged on 4/7/2015. They messaged me through AL for a good contact number which I provided my cell number. I called the company with no answer and left a voice mail on 4/11/2015. They Message me again through AL on 4/13/2015 saying they tried to call and asked for a better number. I believe they lied because there is no voice mail or phone record of them ever calling my cell or house number.  I replied asking to cancel with a full refund. I never heard back from them and still no refund as of 4/23/2015.
