ICON FITNESS, LOGAN UT Ghost Charges Liars Logan Utah

I purchased a Nordic Track Treadmill and applied for the Fortiva credit offered through icon Fitness. I paid the treadmill off completely. I have all the paperwork reflecting this fact. Three months ago, out of the blue, I received a charge for $149.00 dollars on my card from Icon Fitness. There was no description of what it was and I did not purchase anything new from them after paying off the treadmill. I called their billing department, and have spent a total of logged 3 hours and 42 minutes tying to get a hold of someone to dispute this amount. I did get a hold of a woman named Vicki on 11/28/17 who said she didn't know what the charge was for, and she would take care of it and send me a follow up email. I never heard a word, and of course a new statement came in the mail with the 149 charge on it. Now I am taking hits on my credit report and STILL cannot get a hold of a representative to help me. I fear I may need to take legal action over 149 charge to preserve my credit score. I cannot close the credit card with out resolving this bill first. One I dont even OWE!! Icon Fitness is a SCAM!! It has horrible horror stories all over the internet, and unfortunately I am caught in their deceit.
