Refund of Payment

I had paid Vodacom via EFT for my account, in the same month they debited the same amount, i have been trying to get Vodacom to refund me since November. this week i get an sms stating that i need to FAX them proof of payment, i called their accounts department and advised that i dont have access to a FAX machine (who does) and i would rather prefer an email address if this is available, (i mean really). they provided me with the email address i have then sent the proof of payment through 3 THREE times to date NOBODY has responded, this morning i call the call center and they tell me their system says that they awaiting A FAX FROM ME!!!!! this is ridiculous as this morning the first email i get is from vodacom EMAILING me my statement for the month thus far!!! pathetic! nobody knows what is going on, either nobody's systems talk to each other or everyone seems ***********
