Very unhappy and would like to solve this problem

Good day As per our telephone conversation this morning: I purchased a Fiesta ST 1.6 eco boost Gdti from Auto integrity finance at 154 Stilgelee Avenue, The Willows. Pretoria on the 17th of April 2023. I had the vehicle in my possession for one month and it had an engine malfunction. It was collected after the notification and I was given a courtesy car for 3 weeks after which a received the vehicle. I drove it for another month and it had a bearing knock in June it was then collected from my home after 2 weeks on a flatbed on the 6th of July and I never received it back to date. I kept on following up and each time they promised to get back to me. My mother followed up as well and they blocked all her contact details. I asked for a swap and it could not be done. As a result of me having to fix another car to travel to work, my Cell contract debit order bounced back, it has since been paid up and closed. I then request for a cancelation and it was declined immediately. Please assist as I cannot pay for something I do not have and the dealership is acting very shady and unprofessional as they are not willing to assist or meet me halfway. Should you require any additional information, kindly contact me on *** / ***

Yours sincerely
