Rent to Buy at Geely

Hi I went to Geely at Midrand to Deposit a Car for Rent to by and I got it and they signed the contract for three years and informed me that when I no longer need a Car I must inform them in three weeks, but to my surprise is that on Saturday morning I was told that we are here for the car but I was not informed in three weeks now, that we will come to take the car while I was paying it and I only jumped two weeks not paying as I was blocked and I was looking for a driver for the car so is that the way of treating us or what is it a good way of doing things with us without informing us that they will come to take the car or not in these date. Please I told them to bring my deposit back as I paid them and not being informed that they are coming to take the car back which is now a breach of contract.
