Damaged my property

Do not trust this company to install your trackers without supervision, mine was installed a week ago, less than 30 mins and the technician couldn't leave quick enough, when turning on my 4 month old car after that the engine light came on, there was absolutely no power to my car when driving, I took it to the dealership for a diagnostics report which has come back that bolts and wires to my airflow system were loosened and damaged, now Tracker SA insists on attaining my report that they did not pay for before they investigate anything, as per our legal representation we aren't legally obligated to share this with them until such time that they investigate the matter, I have asked for the installers compliance certificate which I get ignored on, I have also as a test pushed both emergency buttons in both my vehicles and not received any response from Tracker SA thus to me meaning the systems are redundant, but park your car in your premises and you will randomly get called and told a alert was given through that the vehicle was hijacked, push the panic and you get nothing. It has been days on end now with emails back and forth with Nomthandazo at Tracker SA and to date they have not at all started an investigation, sent me the information I have asked for or even remotely apologized for damaging my brand new vehicle, all they care about is the contract that's in place! So legally I am now sharing my horrible experience which to me is definitely in the best interest of the public, all truthful with substantiating evidence.
