Vodacom data network battle.

I do not understand why in 2024 Vodacom department does not have a customer care email. I logged numerous tickets on their Vodacom app but have not received the help I need. I bought a data sim in 2023 beginning of the year and the network has been poor since the start. I have been complaining and want to cancel at this point but can't even do that as no response. They will penalize me for canceling early I assume, but can't provide the service in the first place. Vodacom customer service is useless and Vodacom should not be in business if they can't provide the service. They will ignore this complaint as well.
