Vodacom does not care

Just to inform, Vodacom never game back to me on my issue, still not resolved and they don't care. My info is greyed out and they can't generate upgrade codes for me. I went to store, phones, complained. They logged a call that got escalated every day for a week and then call closed, problem still not resolved. I tried sending email to CEO also just ignored. Being a customer of Vodacom for almost 20 years this is how they treat you, No one gets back to you now feedback. I decided to move to MTN but apparently Vodacom says I upgraded somewhere to early and I must wait till March. I don't get it if a contract does not have handset installment and they don't want my business why not let me go.
