Tired of these ****mers

I am being harassed by these ****mers called RCS/Edgars. I made 2 purchases in January of this year. I paid casg onto my card on both occasions and then bought the items with the card. Since January 2024 up until about June or July they owed me money. I think my payment was just over R30. All of a sudden during September and October I get non-stop harrasment phone calls asking me to pay my account. When I finally looked at my statement last week I found I was all of a sudden subrscibed to something that I have absolutely no knowledge of. And some other fees are also suddenly appicable to my account. So since they can't make money of me in other ways. They *******ly bind me to I don't know who and what. Furthermore they tell me to contact BLTS because it is their subsciption. Who the hell is BLTS and what service do they provide? My other concern is that this appears on my Edgars account but Edgars is not taking responsibilty. This is utter ****
