Had a VIPER security system/remote start installed in my brand new Dodge 1500 Truck. Thought it was the greatest thing since sliced bread. Price seemed reasonable and it worked like a charm for a couple of years. Had no complaints UNTIL I had a problem and had to contact them - YOU CANT CONTACT THEM. They are a large diverse company with several divisions and NO HUMAN TO SPEAK TO. The first problem was that my subscription ran out and VIPER stopped working. I had paid for a 3 year service and it just stopped. I could no find a Customer service number and, in desperation, contacted these jerks by email. Days later they responded saying that my subscription expired. How about sending me a reminder to pay my bill. Nooooo... just let it expire, have the customer try and trouble shoot the problem and communicate by email. How f-ked up ??????? I paid and turned the service back on and then it started acting funny like asking me to re- login every time I opened the app - which it never did before. Now the app wont even open and Verizon said its not their problem - contact VIPER - GOOD F-KING LUCK - u cant speak to a human - just send emails back and forth trying to solve the problem. STAY AWAY FROM VIPER AND DIRECTED ELECTRONICS - THEY SUCK
