Still waiting for my refund

So after i wrote a review on hellopeter, Vodacom finally resolved the issue of a ********** upgrade that was done on my name and i was grateful. However, till to this day, i am still waiting for my refund for the payment i had to make during that period. I was told to send proof of payment and bank statement to ********** which i did. I called and i was told that they did not receive the attachments on the email... please note that this is the excuse they gave me when i first reported the upgrade that was done **********ly. I have noticed that this is an excuse they give to a number of people. I was a happy vodacom customer until last year November. Couple of weeks later, after resending it, still i do not have my money. This has been an emotionally draining experience.
