Worse experience of my Life Vodacom

I'm a Vodacom customer for more than 25 years. Got the worse experience of my life. For the first time I did an upgrade and reinstate my contracts over the phone. This ends up in a total disaster. We did discuss the charges on each device. My account was debited on 25/1 with R800. Nobody can tell me why they debited me. Again I was deibted on 31/1. My normal account. Again debited on 28/2 with double the amount. Nobody can tell me why. I went to the Vodacom shop in Mooirivier Mall Potchefstroom and again I experienced bad customer service. The consultant talked over the phone 3 times with other customers. I walked out of the store. No customer service. I phoned the helpdesk 3 times. Waiting for almost an hour to be assisted. The phone was dropped in my ears two times. I'm still waiting for someone to phone me back. I need to get my account sorted. The wrong number was upgraded and nobody can explain my charges. I need this to be rectified. I send an email to ********** yesterday. Customer care told me this is the only mail address they have. Nobody contacted me yet. I again went to the other Vodacom shop in the mall. They told me the only way they can assist is for me to contact customer care. This is totally unacceptable. When I like to upgrade my account. Everybody willing to assist but when there is an error on you account. You don't get help from anyone. I need someone to contact me to help me resolve this issue. Unable to get any assistance for Vodacom on phone or in store.
