Extremely poor customer service

I have been trying to change my surname to my married surname on my Vodacom account for two months. I have phoned the call centre repeatedly, with different responses depending on the agent I speak to. I was then told to email the relevant documents through in order to get the change done. I have now emailed them 3 times with no response. I even tried emailing via the website that promises to get back to me in 24 hours. I have tried twice and BOTH times - no one from Vodacom has contacted me. <br> <br> Vodacom - your service has more holes than a block of Swiss cheese. Sort it out.
