Payjoy selling double the price of products

Bought a phone worth R3699 April 2023 and according to payjoy assistant was that I will first pay the downpayment of R 925,00 (25 %)and R780 within 7 days then pay R 780,00 per month for 9 months or R180,00 per week for 36 weeks. The total amount that would have been paid after the 9 months term that you have chosen will be R 7 945.00..Acoording to payjoy assistant and the team as ive discovered now.Payjoy is selling incorrect products to customers 🤔 where on earth can a person be buying a phone of that amount R7945.00. I should have been paying R221.00 per month for 9 months after minusing first total paid amount and R780.but its not the case in that according to Payjoy.

The are saying that no interest is added because should you miss the payment or make late payment the balance will remain the same, no interest or late payment fee will be added however the total amount paid over 9 months cannot be the same as the cash payment..again it's not worth it. A day light ******* to customers..I alert anyone NEVER BUY PAYJOY PHONE BECAUSE THEY CHARGEY DOUBLE THE AMOUNT COS***** not saving as they say
