Refund not refunded

I then took it back. The Accounts Manager promise to refund my money within 7-10 working days since my payment was done by a guaranteed cheque.<br> <br> between the Wednesday and Thursday leading to 04/04/15 I made a total of 6 calls following up on the matter. at first I was told the person handling my issue went to a funeral, then later I was told they will call H/O and get back to me. no 1 ever called me back. I went to the store on Saturday the 04/04/15 to find out what is taking so long. I was then told my refund papers were never sent to the H/O. I must fill in papers again since the person who initially assisted me is no longer with the branch.<br> <br> I find this utterly disturbing because my money with makro means I could hav earnd a month's interest on it. but I cant even spend it since they hav it. when r they paying back the MONEY
