Shocking service from ADT

I installed my first alarm in 2007 and had basically no problems or false alarms in 11 years. In about 2018 I had the alarm serviced by ADT and they advised me to upgrade my system- which cost me thousands of unnecessary rands. Money waisted. My family’s nightmare started immidiately and it’s even worse now. Since the day the new system was Installed I had numerous weekly false alarms, beeping and other problems . I would think that the ADT technicians was between 15-20 times in my house to fix it - to no avail and most of the times they want to make changes and that even cost me more money. I demand that they re-emburse me for this new system as well as the monthly money that I paid since it was installed because I didn’t have one month’s full service. We even have to sleep in anther room as the beeping is irritating. I challenge ADT to share with us how many times technicians was send out to my house and how much money I wasted on the new system as well as the monthly fees. I’m gatvol and fed-up now as it is 21h30 and this thing started beeping again. Even if it is not activated it beeps randomly. The alarm also went off about 20 minutes ago for no reason. Please help me to de=install this system and re-install my old system as it absolutely can’t go on like this. I’m fed-up of technicians being at my house every week as well as we try to be safe with the COVID - but they keep on caning back and it’s getting worse. Please help me with this absolutely a very bad situation. Regards Kobus
