Lisa Cars adds money to their selling price when doing a finance deal.

Dear management. Please help me with the following query. I purchases a car from your branch in Fourways in June 2018. The car was listed for sale on your webpage for R89 900 (proof attached). But on reviewing my documentation I see that you conveniently added an amount of R5772.99 to the buying price. I supp**** a deposit of R50 000. You conveniently added another R6130.43 exc for a delivery fee, but I picked the car up at your branch and did I did the licencing on which you refunded R600+-. On the R39 900 I wanted you to apply for in finance, you (Samson) app**** for R54 341 ( Then also added was a useless motor guarantee of +-R17500 making the total 67 574. 29). I only wanted your help in making arrangements for finance, instead you sponged a customer. How many clients have you fooled and taken more money than you needed to take. I deem this as *******.

The ****y accountant whom "explained" this to me made it sound as if all this is normal, and I received no answers to my questions.

I kindly request some answers please.
