Refund taking forever to be processed !!!!!!!!!!!

I am getting no help with regards to my refund. This is the 3rd email I sent to hello Peter with regards to my refund . The manner in which @ Vodacom they dont care I am fed up. Today I call Vodacom they saying the refund is logged with subscriber collections. At subscriber collections they cant assist they saying the refund is with the legal department . I received an email that the refund has been processed but when I call I am told they need proof of payment .TOTAL CONTRADICTION. I have to wait 7 to 14 working days when it took me 5 minutes to make a payment at the store but when I should be getting my refund there is a delay for a full 2 months I have been waiting for this refund , I am really tired with Vodacom.Client satisfaction and customer care its really poor.
