The new online ******** in town

I purchased for a 36 month tracker contract online on the 17th of December 2021, transaction went through and the money was deducted from my account. I chose the nearest fitment centre to install the tracker and the email confirmation notification was sent to visit the selected centre on the 22nd of December 2021. Upon my visit at the centre, I was shocked to find out that they did not know of such an appointment and required a special installation reference that Matrix should have given me and confirmed my appointment either via text or voicecall. I tried calling their call centre, the line was busy for the whole day, literally! From the 22nd of December 2021 till today 04 January 2022, the line is still busy?! I sent them an email on the 3rd of January 2022 to formally complain, they just sent me an automated email saying my complain has been lodged and they will respond. Only the good Lord knows when that is. They literally took my money, for free, no services, no installation, I am gobsmacked, just like that, talk about the new modern-day day light *******/******s.
