Linder Security is the rudest and most unprofessional company. Comcast had messed up my security system, so I asked Linder to cancel the service. Linder refused to stop billing me, even though I did not have service. I had no contract with them. I paid them $450, and then they had the gall to send me another bill.\r
I called and asked them about it, and they hung up in my face!!\r
Unbelievable.
Cons: Charged me $500 for services not received
