Very bad service

I'm so disappointed with vodacom I went to Menlyn Vodacom to pay my account. A month later I see that the money is not reflecting on my statement I called vodacom to enquire they told me to send a email with the proof of payment to a pop@vodacom email address, the following day the lady from vodacom contacted me to let me know that they are working on my account and the amount will reflect in seven days, it's been two months now the money is still not reflecting. Vodacom I want my money.
