Explora upgrade *******

Wanted to renew my explora 24m contract at the end of Nov 2021. I was notified that Multimedia and Satellite would be contacting me to do the installation. They never arrived so on the 8 Dec i cancelled the upgrade. After calls and emails to dstv i am still being billed over the last 3months for a new decoder i never received. What a *******. I am collecting ref numbers from dstv but no action from shocking customer care dept They only option will be to cancel my subscription and debit order.
