Disregard for Customers

I pre-ordered a game for the 29th September, this was never delivered. After I had to phone to find out why, I cancelled my order. Was told 7- 15 working days for refund. The game was then delivered to my house on the 4th October. I phoned to tell CNA that the game was delivered, they then went on to tell me that they would collect the game and THEN only would my refund be processed (another 7 - 15 working days after the game is collected). Game was collected on the 5th October. It is now the 30th October, CNA does not know that the game was collected (they also didn't know that the game had been delivered). And I am out of R900, which I need this month since I had to by the game in a proper reputable gaming store. It would have been simpler to sell the delivered game, at least I would have received money. So thanks to CNA I am out of R1800, tons of airtime and time used to contact etc. And nothing is being done to rectify this. Seriously regret using these services, will not allow those close to me to make the same mistake... However can I have my money please CNA? Or will you be paying my bills this month??
