BAD SERVICE AND VIOLATING POPIA

I took out a subscription with Telkom in 2020 when we were told to evaccuate our offices due to hard lockdown. I paid my account but never received the proper service because the internet was just not working at all in my area. I emailed Telkom and only received one callback from someone who said everything looks fine on their side. I cancelled my subscription and stopped my debit order in 2021. I have been receiving judgement emails and sms' for the past few weeks to pay Telkom for something I have not used for 4 years. I don't get it and I dont understand who Teklkom shared my data with. This is the email address I am receiving these mails from Collections-DebtIN [SM] <***> - I don't know who they are and honestly the POPIA Act is there for a reason. Someone needs to sort this out but I am not paying for something I have not had the satisfaction of using. Telkom you need to contact me to directly to explain or even via email to advise me why you have decded to share my data. My account refrence is ***.
