Shocking service

I would not recommend Divan Horn from B and H Electronics - he was paid to install alarms, did a shocking job where the alarms continuously went off, we tried to contact him to come and fix the issue, he did not answer calls, even though he was always on his phone - eventually responded to messages, sent a different person to come and sort out the issue, however the guy arrived with absolutely nothing, he left and has not come back, no communication from Divan the owner either. Absolutely shocking service and shoddy workmanship. Highly unprofessional.
