BLC refusing to pay back my money

I am so livid... On the 03/10/2025 I received a delivery following an order I made online. I ordered a double deal Samsung cellphones but what I received was a single Nubia Music cellphone, which I did not order. Already a debit order mandate was loaded (still is) to my bank account. However, I returned the item after summoning BLC to come collect their phone. They did and I requested for my order to be corrected, so I could receive the correct order I made. They declined, citing that I would have to cancel the entire order and continue to make another (to which I conceded). To my distaste, they still have not contacted with regards to a new order. To make matters worse, their debit order of R480 + R150 pulled funds from my account nonetheless, end of October 2025. I have made several requests and demands for my my refund (including cancellation of debit order mandate), but I am not making any head way. Recently they contacted me, requested my bank statements and also mentioned that I will be penalized for cancellation of the contract.... I want all of my money and not a single cent short...Hellopeter, may you please instruct this BLC nonsensical company to pay back my money???? I am so sick of this BLC nonsense...
