Licences department

My name is Mthandeki ID no ***. 2019 on the 5th month I received money from my aunt pension to start a business, and I decided to purchase 2 by 10cubes trucks that I've registered on my name, the plan was to get them to work on mines and powerstations, Covid started and disturb the whole plan, then 2021 I renued license disk for the trucks and 2 other vehicles I have. 2022 I did not have enough money to renew the license disk, which costed me R25000 for 1 truck. With the lack of knowledge regarding the outstanding balance of the unrenewed licence of the trucks now I cannot access the license disk for the other vehicles for 2022. I do not have money to pay for the trucks that have interest that increases everyday. Now I do not have a plan to get the money that is needed, I am owing them a lot of money and the fact that it increases everyday makes it worse, kindly assist on getting a discount and getting the amount owed not to increase. I understand that I need to pay them but not so much, as I have stated I do not have a plan, now that I do not have a disk for the vehicle I use everyday for work makes life very difficult. PLEASE HELP ME OUT
