Unhappy client

I was fortunate enough to have had ADT when they where signing up new clients, in my area in 2021. Unfortunately, we went south. On more than 4 occasions, the security personal did not arrive when the alarm was activated. Adding to this, the premium increased considerably. I was originally linked via the Telkom line. When this line became redundant, the security company did not inform me that it wasn't getting a signal. Despite me paying both accounts on time, I was receiving no service. Subsequently, I noticed that my neighbours were also changing their security companies. I asked around & lo & behold they were paying more than half of what I as paying. So, I changed company. Now I am being handed over to collection agencies who have threatened me with legal action, should I not pay. The Telkom device was handed over at their Overport City branch & I no longer have a line. Despite this I am still receiving threatening calls and emails regarding this non-existent line. The date, time & person who was given the device, did not log onto their system that I had handed it in. She merely said, thanks & dumped it into a bin. If Telkom had any trained honest employees, they would have done the legal thing, but she did not. After explaining this to another Telkom employee, I received an sms which said that the account is closed, but the collection agencies believe otherwise.

Please help !!!!
