Cancelled order on 9th of Dec still no refund

I have ordered (8th of December 2015) and paid for the incorrect item , which I notified Incredible connection on the 9th of December 2015. I then reordered the correct item. The second item being cheaper than the first item. <br> <br> Incredible connection has from the 9th to the 22nd of December still not reimbursed my funds. <br> <br> Every time I phone , I get the run around that it has been emailed to the accounts department, apparently the accounts department does not have the simple technology of telephones so I cannot contact them myself.<br> <br> Incredible Connection has got 24 hours to reimburse me the funds or I will take further legal action. I do not care how they accomplish this. They can provide me with a cash pay out at their nearest store.
