Service of the Alarm system

I have alarm system with your company and three years lapsed in June 2015 and i am on month to month contract with them. I want to know as to who owns the device (alarms system) and who should service it? The remotes they gave me aren't working now, the battery switches off the alarm when we don't have electricity. <br> NB: I want a complete response not something like \It depend on the contract you have with us"";NULL;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ***;818443;23;1;2;0;1;0;0;2;NULL;NULL;NULL;15/10/29 9:41;15/10/29 8:13;**** PROMISES ;8,91E+12;Hendruk Pretorius;***;The Manager \Hennie\"" from Standard Bank phoned me at 10h59 from the number ***"
