WefinCars Treated Me Horrible as a Woman and First Time Car Buyer

I wanted to buy the Car from Weelee initially, however I didn't qualify to get funding from the bank. And I didn't have cash as the Car was 279 000. Then I was advertised to buy through a company which is based inside Weelee warehouse which is Own to Rent. As a first time buyer I didn't know much about how it works etc. I completed the paperwork and was asked to pay 5K to secure the car so it can be taken off the floor. Then was moved to WefinCar got helped by Moses I was asked to pay 100K cash as the deposit. Went to sign the contract and the price went up to 754 000 my installment was 13K including everything car, tracker, insurance and roadworthy. Everything sounded good. I arranged to collect the car,, nothing was expled in details except that I shouldn't miss the payment as I will loose the car if I do they take it. I have never received the invoices whenever I made payments. Apparently it must send via email which never happened. And I will be asked to resend it whenever they didn't seem to see payments made, even after sending POP on their WhatsApp group and them acknowledging receiving payments. My experience has been a nightmare from day one it has never been great especially for a first time buyer of a vehicle. In February I missed one payment which I tried making an arrangement with the Wes I am not sure what is his position there. He's the biggest asshole I have known, you can't reason with I'm. When you try to remedy or ask to make arrangements he makes things worse. It's like giving someone an immunity to abuse you. He doesn't understand nor have remorse. So in February my money delayed in coming through which I tried to explain to him so I can be given grace. Considering that I have paid so much money this far for me to loose it over a small amount which is the installment but he refused and the car was collected in February this year, And he told me he's cancelling my contract. So if anyone who knows what one needs to be done going forward please help I need as much help as I can get.
