Vodacom's poor customer service

I've been with Vodacom since 2013. That's 10 years. The service I'm receiving from them is rather ridiculous. They extended my phone contract with period without saying a word to. The contract was initially 36. From December 2021. When I checked the status of my contacts I realised my contract is actually 41 months. I've called a number of times for clarity on this but I was sent from pillar to post. Even went to The Glen Vodacom were an inquiry was lodged and I was told they'll get to me I still have not heard a thing. I'm really disappointed 😥
