had this time ans again with main dealers any fault and dealer blame not factory items, first port of call is make ghost company aware of problems , i assume they operate the same as others. we used to be cobra dealers and if a problem occured they would send a technician out from head office to check the install and the equipment, most if not all of these installs are done to fitting sheets provided by the main company cobra/scorpion/clifford etc so imagine ghost is the same.
if the fault is down to there product they will be insured, if not they can issue a report to help you proceed.
only had it twice in nearly 20 years once on a brand new golf gti electric window motor burned out , blamed the insurance approved alarm, and tried to disclaim all warranty, cobra proved motor fault and spoke to audi direct where they conceded they had to recall due to faulty window motors.
and ford where car refused to start one morning and that almost went to litergation before ford backed down, again main dealer being a pratt, wasnt privvy to all the details on that because my company was cleared early on and cobra took ford for defamation or the likes. at the time it was well known and there was paperwork circulating stating from ford head office to actively look for any not standard fitted items if faults occured and blame them.
strange thing was we ended up doing most of the main dealer security fitments for many local dealers.
