worst customer experience ever

I called vodacom call center yesterday morning (14 April) because I had a problem with the way my data was vanishing, the lady I was talking to didn't seem interested to help me so she gave me this number (31050) and said I must sms \invoice \",i did that, only to find out that was a service for contact phone users, so I purchased more data and it was gone again. At 21:14 I called vodacom again and the lady I spoke to was so rude I couldn't believe it, She was telling me how I should read my phone manual so I know how things work. I told her she was rude and that's not how you communicate with customers and then she hung up on me,while I was still talking. Is this how you treat your customers vodacom, I'm still in shock"
