Bidorbuy fails to get my refund from seller even though I paid on their platform they left me to deal with the seller myself.

I ordered a lounge suite on bidorbuy in June 2021, had problems with supplier and after no delivery I cancelled the order on 25 August 2021, after almost 2 months of waiting. Bidorbuy has failed to get me my refund back from the supplier/seller who's refusing with it. Today it's 24 January 2022 and I still dont have my money back, instead bidorbuy just keeps on changing the consultants who are dealing with this case. This January they changed the consultant the 4th time, and everytime I have to repeat the same story over and over again. This would not have happened if it was takealot or snatcher, I would have received my refund long ago from these other platforms.
