Useless service

Vodacom’s cancelled their wrong contract on my line. It is now three months later and it is still not resolved. They are happen to take your money but can’t fix their stuff up. My phone line does not work unless connected to wifi. It’s is shocking. That’s what happens when you employ *********** people. Three months later and I’m still battling. Why couldn’t they reinstate my line as it was????? Now it’s my problem
