Refund for unsatisfactory stock returned

I received a bed with missing parts on January 30, 2015 and empty promises was made to deliver the missing parts and after fights and calling the stores head office i was eventually told that the parts could not be located and I should re-select another bed. i did reselect the bed which was subsequently delivered on the 23rd of June upon realising that the bed could not fit into my house i requested a refund as I had sent back both the bed with the missing parts and the replacement bed as well as the mattress. I emailed head office the next day about my request for refund and the indeed confirmed the receipt of the goods and was promised a refund in 3 day up to this day i get all sorts of excuses from people processing not being at work, to managers doing follow up, and systems not working and today i was asked to confirm what my refund amount is and that is after i have called to inform them that the said refund that was due to be received by me on Saturday was not received. And lately they are telling me that they are doing a reconciliation on my account to establish the correct refund amount. BEYOND DISAPPOINTED WITH THE TREATMENT I RECEIVED AND I HAVE BEEN MORE THAN PATIENT....
