Makro Delays Refund

Our Company made an overpayment to Makro Montague Gardens in January of this year. On the 16th of February 2015 I sent an e-mail to a Makro accounts person that I was told to liaise with. She only responded almost a month later on the 10 of February 2015. She then gave me documents that needed to be filled and I filled the documents and gave her the proof that she said was necessary for the refund to be processed. Since then she's told me that Makro wants more information from us. What annoys me is why am I told information in drips and d***** ? It appears like a deliberate stalling tactic from Makro to not refund our money. <br> <br> Makro has been given a bank statement with the Makro payment shown on the statement. They have also been given proof of payment as per their request. A week or two after the information they requested was delivered, they now want more stuff ?!
