Please ASSIST

As per my insurance, I am suppose to get a tracking unit in my car, great stuff, Tracker phoned on Saturday, confirming, giving me a price and setting up the installation date. All good, I phone in today, reason work issue and i need to help out in another area, I want to reschedule the area, I speak to blessing, who started off good but ended terrible, during my explanation, he told me that my account is suspended and that I owe R1000 some change for a invoice in 2019. I tell him wow 2 years later and no this and that no one on Saturday told me about this, I then explained that I needed to get this done, I understand that he might not be able to assist me but is their a Manager or someone I can speak to and get it resolved. He said he will transfer me to the installations department, I asked again how can I get this resolved and he just transferred me. WOW. I then spoke to Zandi brilliant service rescheduled for tomorrow at 08:00 at the new area. But I still have not been assisted in the suspension matter. Can anyone assist me n getting this resolved I mean really, this is why Tracker has so many complaints on Hellopeter and other social media sites.
