Pathetic service from Vodacom in Oudtshoorn area

I am utterly disgusted with the lack of service from Vodacom. I took out a new sim only data contract with them when they were running a promotion in August 2019. Since then I have been experiencing bad service, but around the same time lockdown started in March 2020 the service has been non existent. Every time I have contacted customer care due to slow internet speeds or no data coming through they just say it is due to my area and then offer a cancellation quote after I told them I want to cancel. I still have not even received the cancellation quote after numerous attempts and they must not think they are going to charge me to cancel a service I pay for every month, but don't receive. The irony of the matter is if I go to my place of work, 1 km away, I get great internet speeds and everything, but in the residential area I live the speed is currently 0.24mbps download and 0.13mbps upload. I work full time and study part time, how am I supposed to do my studies and assignments with that kind of internet speed. I also went to the Vodashop and they are aware of the problem, many other customers are also complaining, but it seems after a year Vodacom still does not deem it necessary to fix the connectivity issues in this area. It's literally in the centre of a medium sized town with two Vodashops so clearly enough customers here to try and render some sort of service. This is pathetic and I will be going to the consumer protector if Vodacom does not refund me for the time I paid and received no service and sort out their service issues.
