Extremely poor management of complaint

I purchased a vacuum cleaner: AEG/Electrolux from this branch in June 2015. The item worked but did not suction out the dirt. I returned it to the store, Joash, in July 2015 and have not heard from them since. I stopped by in August, almost a month to the day that I left the item with them only to discover that it was still lying there unattended. DISGUSTING service in my opinion. Maybe the employees of House and Home don't clean their homes but I certainly purchased a vacuum cleaner to use it not to let it lie at the store. It did cost me R1 069.
