Disgusting Service - Worst Nightmare

It have received the most horrible service from Netstar for the past 9 months, yes 9 months. Since the beginning of this year when I purchased my vehicle. I called Netstar and requested a tracker installation, they took all my details i.e Name, Banking details, Debit Date etc. On the day of installation, 2 gentlemen came to my workplace with a very old and unbranded car, and they told me they were sent by Netstar to install a tracker on my car. I was bit concerned but because they were wearing branded t-shirts, I let them complete the job they came for. When they were leaving, I insisted to them that I needed an installation certificate so that I could hand it to my insurer so that my premium would be less. I received a SMS confirming the installation but to date I have never received an installation certificate after asking for it a couple of times. Problem number 2, Netstar has been debiting my account on the wrong date which is 21st of every month when I told them clearly that they should debit on the 25th of every month. When I called in to ask them to correct this, they told me that they can’t speak to me about this matter because of the POPI act and they have my wife’s details on the system. I don’t know how they got to this conclusion cause the ID number and banking details that are there are mine. After failure to get this corrected, I asked to cancel the service, they told me cancellation would be R600 some change and somebody would call me about the cancellation, but my wife would have to cancel, not me (surprising). For months I’ve been incurring unnecessary bank charges because of Netstar debiting on the wrong date. My bank statement looks like a mess with bounced debit orders from Netstar and this is affecting my credit rating negatively. Netstar is now telling me about this balance that I owe and a hefty cancellation fee after this horrible and non-existent service that I have received. 1 – I have been getting R100 a month in bank charges every month from Netstar, 2 – haven’t been able to get lower insurance premiums because of Netstar’s failure to provide me with installation certificate, I don’t believe that Netstar would even be able to find my car if it were to be ****** if they’re unable to handle such small things.
