Why is it so difficult to cancel the order and get my money back?

I was contacted in 2023 for products, initially I agreed I wanted the products however a few days later I contacted the company to cancel the order. The sales lady said she will move it to the new year Feb. I then called again in the new year before money was debited from my account to advise them I am no longer interested and the debit order must be canceled, so I don't want no debits from them. I was advised someone in the cancelation department will contact me. End of Jan 2024, a debit order went through 😡😡😡 and this is AFTER I called to cancel the order. It's been weeks and I have been told yes someone from the cancelations department will contact you, to date nothing. I've been told a consultant tried to contact you but there was no answer, WHAT A LIE, I work on my phone and literally ALWAYS looking at it. I call the call Centre daily and I'm told someone is calling you back shortly. Frustrating that I don't have their products (and I don't want them) but they are sitting with my money, how? I want my money!
