Arrogant Manager gives poor service

In the month of August 2015, my partner (Douglas Danso) purchased a lounge suite for over R25 000 from Bradlow's Randburg. The service we had initially received from the sales assistant was superb so I our disdain does not lie with her (Phila). However upon the day of arrival the one leg of the 2 division couch somehow slipped inside the actual couch so it is now supported by three legs as opposed to four. I have reported it to the store manger Dave, and I was told it had been booked for service on the 7th of September. However, EVERYTIME I do a follow-up I am told that it has been escalated to head office and nothing else. We are highly FRUSTRATED at Bradlow's incompetence and arrogance in their lack of communication and mobilisation of actual solutions. I have had to live with a wobbling couch for about two months!! I am left feeling helpless as I have communicated my frustration with Bradlow's to no avail. HELP.
