Upgrade issues with Vodacom

I have tried several ways to upgrade my contract with Vodacom, but as each year I struggle, from phones arriving damaged to contracts being canceled by other people This year as usual, a problem, can't get the contract I want, can't log into the Vodacom app because another user is using my number, I call the upgrade center, refuse to give me the deal advertised.... Eventually after more falls they accept my upgrade at the advertised price. Yay,y upgrade is done, but NO, now I find out my upgrade is canceled, AGAIN!! Really after more than 20 years with Vodacom this upgrade nonsense has me wondering of its time to change service providers...
