Vodacom too Big to worry about clients

I have upgraded 2 phones, very early in July 2020. I received one phone. Since then, I have to phone Vodacom constantly. They say phone was hijacked at RAM. RAM says they sent letters to Vodacom but has not received anything. Everytime, someone will follow up and get back to me, and then another week pass. Now, 2 months later, I am STILL waiting. I spent over R45k at Vodacom last year. Maybe it should be the last year that I am with Vodacom. The 45k is probably not worth much to such a large business.
