Business ProfileforNationwide Interlock

I had an interlock device installed in my car. Within a week I received a violation before blowing into the device, I go and have it unlocked. The very next day I go to work and after a 13hour shift get in my car to use the device. Before I even blow into it the display screen has an X saying lockout in 5 days. I call explain my issue, they schedule an unlock appointment, but advise me to call the *** to make sure I dont have any violations. I did and do not have any violations. I show up to the shop as scheduled today the technician ***** advised its an issue with the device stating its not my fault and I wont be charged the $75. I have now received two seperate text messages and calls stating I owe $75 for the unlock fee. I am not in any violation, and the device given to me was faulty and replaced. Im not paying another $75, as Ive already paid $202 $52over the original price quoted for the device each month. Online it states free installation and monthly service fees includedno hidden fees this is wrong because once you get the contract it has all these hidden fees on it, but after you get it installed. This is bait and switch at its finest. I will get this removed and already found another company that doesnt charge these bogus fees.
