Fed up with threats from Tracker

On the 30th of August I received a call from a Tracker call centre agent with regards to their Tracker Guard app. During this call the call centre agent never mentioned anything about costs associated to this app and I agreed to making use of this service of the Tracker Guard App. I was told that I could add dependents at no cost and decide to add 3 dependents. After the call I received an email with information on the App and a link to download the App. I never downloaded the App and on the 25th of September a debit order for R513 went off my account. Upon investigating this I was informed that I was charged an amount for myself, my 3 dependents and a pro-rata amount for each. I have disputed this with Tracker and the Customer Service Consultant Nomthandazo Hadebe has been very helpful in getting that resolved after I explained to her that I am being charged for something I am not using and that no charges were mentioned in the call with the agent who sold me this Tracker Guard App. What I do not appreciate is the sms's about being taken to their legal department due to non payment. I have been a customer of tracker for almost 3 years now. Tracker needs to treat their customers better. I have received threats about being taken to legal and to have my services suspended. Tracker can go ahead and suspend my services but I will not allow any company who I am paying for a service to threaten me. I do not appreciate that at all and I will definitely not be making further use of their services. Customer service needs to improve drastically.
