Dealt with Bav at Grand Alarms for the sales/installation stage - all went very well, was told that I'd have a wired alarm on the main floor, wireless upstairs. Installer came, he inspected the main floor and basement and indicated that he would have to install a wireless system due to a number of reasons. The installer than told me that I would have to call his boss to ask if that was OK. I called Grand Alarms, and spoke to a manager who then passed me onto Bav. Bav indicated that I would have to pay an additional $375 for the wireless hardware. I indicated that this is unacceptable because Grand Alarms had already agreed to install an Alarm System in my home. It should not have been my issue that the sales person did not travel to my home to appraise the best system for the home prior to creating a deal with me that obviously wouldn't work for the home. I pushed back indicating that I would not pay the additional hardware costs (I had already agreed to a 5-year contract with Grand Alarms). Bav called me back, said to tell the installer to go ahead and start the wireless installation as they would cover the cost of the hardware. The installer then starting planning out the location of the wireless contacts. 15 minutes later, Bav called me back and indicated that his boss wouldn't approve waiving the hardware costs, and that I would now have to pay $275. Again, I said that I would not be paying extra for the hardware as I had already signed the 5-yr service deal based on Grand Alarms providing the hardware for the Alarm Installation. It is not my problem that the salesperson did not travel to my home first for an appraisal prior to forming the deal for the alarm system. Once I said I was not paying for the extra hardware, I was then told to tell the installer to stop the installation process and leave. So after having the agreement in place, taking the day off work to be there when the installer was coming, wasting 3 hours of my time in the morning arguing with the sales person and installation managers to have them hold up their end of the sales agreement, I was left without an alarm, and the sales person made the 5-yr agreement I signed invalid. I found Grand Alarms to be unprofessional and unethical (I already had an agreement). I will also be reporting Grand Alarms to the Better Business Bureau, as I had an agreement with Grand that they defaulted on because their sales person did not do his due diligence prior to drafting the agreement. Would not recommend Grand Alarms.
