Poor/no signal for more than 8 months

I’ve been reporting poor signal in my area. I am missing urgent and critical calls. I signed a sim only contract which will expire in November 2021. I enquired about contract termination costs and I was told to pay R2400 to terminate this contract. I find this unacceptable, I am paying for a service that they are failing to provide. I didn’t take their device why is it an issue to terminate this contract? This is pure ****************. I am sick and tired of Vodacom I want to port to another network. I have been reporting this issue for months now.
