Blue label ****med me and is still deducting money from my account

So I was at work last year around 3 to 4September.Time was approaching 8:30 or 9 am if im not mistaken when I received a call from a lady saying she from blue label connect aka c connect offering me a deal for a new phone ,she asked for my info to see If I qualify and I said why not give it a try and so I did.Turns out it was the worst decision I ever made my whole life ,she checked and told me I qualify for a Samsung A24 plus data and minutes for R259 a month for 24 months I said ok and provided her with the last info she asked for meaning my bank details.end of that month they deducted and after a couple days a courier dude called said he had my parcel I was at work and have set the delivery to home ,I told them I cannot reach them at that time and because of curiosity asked what kind of a product it was he said only a SIM card I was surprised and asked what about the rest meaning my phone he said since I'm not around he'll come back 2 days after with all if it's available at their warehouse ,long story short he didn't comeback they deducted money the second month also so I got their support email and spoke to them to refund me and cancel my application and debit order and they never did cancel it only refunded me to deduct again the other months now it's January no refund for my December money they don't even give me proper replies but ai messages saying to call them but with what since they took my money I'm so disappointed don't know what to do cause this thing keeps going on and on
