False advert

On the 21st March 2020 I ordered Marlo 3pc 4kg Double Mink Blanket Combo which was on special . The advertising price was R125. 03 over 24 months. I received my delivery in 3 days including statement indicating that amount due is R125. 03 months end. Today I got a statement indicating that R159. 03 is due by 30/04/2020. I called he choice to enquire about the difference and the senior consultant told me that the advertising amount was false and there is terms and conditions that I accepted when placing an order. Therefore, my installment for 24 months will be R159. 03. I have proof of two different statements. I'm not happy with their service as this looks like a **** to me. They can't advert their product with false amount and claim a customer has accepted terms of conditions this is totally wrong. I will never buy from them I'm done with them.
