Fidelity Security not facing the music

During February our offices performed extensive repairs to our security systems following a lightning strike. On 23 March we suffered a break and suffered severe losses as a result. It turned out that no signal was received by the control room and as a result our insurance claim was rejected/reduced to an ex-gratia payment. What is more is that it turned out that no signals have been received since the day of the lightning strike !!! and by implication Fidelity has failed to properly install and test our repaired system. <br> We approached Fidelity in a very reasonable manner seeking compensation for our losses on the basis that, in our view, Fidelity was grossly negligent in their duties when installing the system.<br> After having to jump through several hoops in verifying the ownership of the goods ****** as well as the quantum of our claim, Fidelity unilaterally rejected our claim on the basis that it was our responsibility to ensure the system is working properly.
