Vodacom email account

I phoned them on the 25th May twice with the same problem. I couldn't recieve or send any emails from my Vodacom account. First I spoke to a lady and there after a man. They couldn't assist me with the problem and said they would logged in a quarey to their Technical Department. They would send me an message with the reference number and I would be helped within 3 working days. The next day I phoned again because I didn't hear from them. The lady said that a complaint is logged in and I asked for a reference number. She again said I would be helped at the latest on Friday. She gave me the reference number ***. This morning I phoned again to ask what the progress were up to date. Nothing has happened - no one phoned me - and I still am without my email. I ask you to please assist me as soon as possible with this issue.
