Vodacom - Terrible Customer Service

Terrible service received from Vodacom. In January 2025, they phoned me and told me that they need to protect my plan with the upcoming tariff increases. I mentioned that I do not want to make any changes to my plans or upgrade as my date for upgrade was scheduled for March 2025 and only then do I want to upgrade and make chages to my plan. They sent me a quote on email which I did not authorize or accept. This was activated on my plan without my permission and when I tried to upgrade now. I was made aware that now I am only eligible for upgrade in October 2026 and my plan only in 2027. I have phoned numerous times and even had the phone put down in my ear and declined. They said they will call me back, but they have not called me back to offer any assistance. Vodacom is quick to spam call you with sales and marketing but terrible in providing existing customer service.
